Available in PDF, EPUB and Kindle. Book excerpt: It is well known that the modern day wireless networks involve a significant amount of video traffic. The present day physical layer standards support high bit-rates so that the HD video could be streamed. But though the bit-rates are high, sudden channel errors are unexpected and unavoidable. This reflects on the video quality very badly. This means there is still room for intelligent solution for efficient video transfer. Cross-layer approach is one of the solution. Due to presence of frame dependencies in video the frames are prioritized and assigned a relative priority index values which is used to provide unequal error protection. Also the transmission deadlines of each frame is different. Thus a time based adaptive MAC layer re-transmission is proposed in this thesis. In this thesis we mainly focus on developing a cross-layer framework for wireless unicast video transmission on software defined radios (SDR). SDR are being very flexible in implementing MAC and PHY layers, helps to easily implement a cross-layer design too. A MAC layer centric cross-layer approach is adopted here. This approach involves choosing an appropriate modulation scheme with the known knowledge of channel state available from PHY layer at the receiver, and relative priority index (RPI) of each video frame from the application layer and adapting MAC re-transmission based on transmission deadline (Td) of the video packet from APP layer. An in-band cross-layer signaling is adopted here, in which RPI and Td are written in the header of the rtp packet. The SNR values from receiver are sent back to the sender along with the MAC acknowledgment. A content aware time based adaptive re-transmission (TAR) and a heuristic modulation selection algorithm are implemented using this framework. MAC and PHY layers are developed on GNU radio with USRPs N210s. Evalvid tool at the application layer for video streaming and evaluation. Results show that the gain in the efficiency is mostly due to the TAR mechanism.

Book excerpt: In another work, we provide a cross layer framework for the transmission of robust packet based H.264/AVC video over DS-CDMA wireless channels with near-ML multiuser detection using linear filters and reliability based processing. A cross layer framework is proposed for both underloaded and overloaded systems. In overloaded CDMA systems, when the number of users is greater than the processing gain, sub-optimal detection becomes more difficult because it is more difficult to separate the users because of the high correlation among the signatures. Such a scenario is of great interest because there are time that the processing gain cannot be increased due to bandwidth constraints.

Available in PDF, EPUB and Kindle. Book excerpt: The increasing demand for video services over wireless LANs and mobile broad- band networks and the challenges wireless video transmission is facing, drives the need to improve the support for video services over these networks. The aim of this thesis is to design and quantify the benefits of new methods that optimise end-to-end wireless video delivery via generic cross-layer design. These new ar- chitectures encourage complex interactions between the PRY/MAC layers of the wireless system and the application layer of the video services. Wireless networks are fundamentally error-prone due to the time varying nature of the radio channel while video services are typically intolerant to data loss. To improve data reliab- ility wireless networks offer forward error correction (FEC), such as the recently proposed application layer FEC based on Raptor codes, and ARQ packet retrans- mission at the PRY and MAC layers respectively. The performance of the WiFi ARQ mechanism is studied in terms of packet loss and packet delay, using time-correlated packet errors generated from a time- varying channel model. It is shown that prior simulations assuming uncorrelated errors seriously under predict the packet loss rate and latency resulting from ARQ retransmissions. The work in this thesis then focuses on the transmission of video over a mobile WiMAX network. The ARQ mechanism of mobile WiMAX is studied in terms of packet loss rate and latency. The properties and benefits of Raptor codes are then explored. In particular, interactions between the mobile WiMAX Modulation and Coding Scheme, the Raptor block size and the Raptor code rate are explored (for various Doppler spreads) via Monte Carlo simulation. This thesis proposes a novel cross-layer design with tight coupling between formats and packets across the OSI layers. A new methodology based on "Raptor- aware" link adaptation is proposed to select the optimum pairs of MCS mode and Raptor code rate in order to maximise transmission efficiency while maintaining a required level of PER at the application layer. Simulation results show that the proposed methodology significantly reduces the required radio resources, whilst offering error free communication to the video layer. To achieve these gains it is shown that MAC SDUs with missing ARQ blocks must be delivered to the higher layers. This can be achieved with the introduction of a permeable layer into the standard OSI model. Simulations show that to achieve the same level of video performance a standard mobile WiMAX system (at low mobile speeds) requires 118% more bandwidth at an SNR of 18dB, dropping to 40% at 16dB SNR. The proposed design also offers an SNR gain of 4dB which can extend the range of video services (particularly useful for multicast transmissions).

This book was released on 2006 with total page 146 pages. Available in PDF, EPUB and Kindle. Book excerpt: This dissertation proposes both coding schemes and system design strategies for video wireless communications. Video coding can benefit greatly from the development of algorithms for optimal intra/inter mode switching within a rate-distortion framework. We propose an algorithm to optimally switch between intra-coding and inter-coding modes for a video coder that operates on a packet-switched network with fixed-length packets. This optimal mode selection algorithm is integrated with an efficient channel encoder. And the framework is further extended to operate on a time-varying tandem wiredline-wireless channel with feedback information from the receiver. We then discuss a cross-layer optimization scheme for the system design of a wireless video communications system. We present a video transmission scheme with adaptive bandwidth allocation over wired and wireless CDMA networks. We derive the statistics of the received signal, as well as a theoretical bound on the packet drop rate at the receiver. Based on these results, an algorithm for efficient bandwidth allocation among source coding, channel coding and spreading is derived at the packet level, which incorporates the effects of both the changing channel characteristics and the source content. Another fundamental tradeoff in the cross-layer design of a communications system that we study is how to optimize the system when there is a delay constraint imposed by the application. The key elements in this tradeoff are the queuing delay in the source encoder output buffer, the delay caused by the interleaver, and the delay caused by channel decoding.

Available in PDF, EPUB and Kindle. Book excerpt: In this dissertation, we investigate problems of resource allocation for uplink multiuser wireless communication channels. The users want to upload compressed video streams with different rate-distortion (RD) characteristics to a base station via a multi-carrier channel. The video is organized in groups of pictures (GOP), and the base station makes resource allocation decisions based jointly on the channel state information (CSI) and the RD information to minimize the average video distortion across all users. We first study the case where the channel is slowly varying. With the assumption of the channel staying constant over the duration of a GOP, we derive an optimal condition for minimizing the sum of distortions in a setting of continuous frequency channel response. Our result shows that for a specific band to be assigned to a particular user, the product of the slope of the RD curve of that user and a marginal rate increment corresponding to that band should be maximized. We then design an algorithm which iteratively calculates the status of the RD information and the CSI in a block fading setting. Compared to two baseline resource allocation algorithms that use only a single layer of information, the simulation results show that the cross layer scheme can consistently improve the performance of the system. We then focus on the case of a channel with arbitrary mobility. To better utilize the time varying channel, we design a pilot symbol assisted modulation (PSAM) system which periodically adapts the modulation format according to the instantaneous CSI. We show that the two baseline algorithms with single layer information behave quite differently as the Doppler spread changes, but the cross layer algorithm performs robustly across all different mobile speeds. We further characterize the capacity gain of using the cross layer scheme.

Available in PDF, EPUB and Kindle. Book excerpt: Mobile data traffic has been exponentially increasing during the past years. With the prevalence of video-enabled mobile devices such as smart phones, more than half of the total mobile data traffics are attributed to mobile video traffics. Since wireless resource is limited and video-related applications are bandwidth-consuming, efficiently transmitting videos over wireless networks while providing higher perceptual qualities at the end users become the everlasting endeavors of the service providers. The rapid increasing demands of wireless video streaming services have boosted the developments of video delivery technologies. In the application (APP) layer, more efficient video source coding technologies are designed so that videos with higher qualities can be delivered with less bandwidth consumptions. Among the existing video coding technologies, the scalable video coding (SVC) provides a capability of adapting to various needs or preferences of end users as well as to varying terminal capabilities or network conditions, which makes it an attractive candidate for wireless video streaming applications. In the medium access control (MAC) layer, resource allocation techniques, including rate adaptations and channel selections, are optimized for better wireless resource usages. In the physical (PHY) layer, advanced data transmission schemes such as multi-input multi-output (MIMO) are developed for higher spectral efficiency. To better utilize the advantages of different technologies in different layers, cross-layer design driven by optimizing the end users’ perceptral quality is highly required. In this dissertation, methods of quality-driven cross-layer design of video transmissions over MIMO systems are discussed. First, a near optimal transmit power allocation scheme for delivering SVC-based videos over MIMO systems is discussed. According to the channel state information (CSI) feedbacks, the power of each transmit antennas is adaptively optimized subject to an overall power limit. Therefore, the SVC bit streams with different priorities are transmitted with unequal error protections (UEPs) so that the quality of experience (QoE) at the end user is maximized. Both transmission errors in the PHY layer and video source coding characteristics in the APP layer are jointly considered in this scheme. A near optimal solution is achieved by decomposing the original optimization problem into several convex optimization sub-problems. Detailed algorithms with different complexities and their corresponding theoretical reasonings are provided. The near optimality of the proposed scheme, in terms of measured utilities, is shown by comparing with the exhaustive searched optimal solutions. Simulations with real H.264 SVC video traces demonstrate the effectiveness of the proposed scheme by comparing with other existing schemes in terms of well-accepted video quality assessment methods, such as the peak signal-to-noise ratio (PSNR) and the structural similarity (SSIM) index. Second, a joint rate and power adaptation scheme for SVC-based video transmissions over MIMO systems is discussed. The ultimate goal of this scheme is to maximize the decoding quality at the receiver side. The rate adaptation includes selecting the best modulation and coding schemes (MCSs), set of spatial channels, number of SVC layers (source coding rates) and their corresponding application layer forward error correction (APP-FEC) coding rates. The power adaptation involves the proper allocation of the power to each antenna in the MIMO system. In most of the existing studies, the bit stream of each particular SVC layer is allocated to one spatial channel and the UEP is achieved by transmitting the more important SVC layers through the spatial channels with higher channel gains. However, in the proposed scheme, the bit stream of each particular SVC layer is distributed to multiple spatial channels so that additional diversity gain can be exploited by applying APP-FEC. The UEP can also be achieved with different APP-FEC coding rate on each video layer. Moreover, transmit power allocation is also effectively and jointly determined to improve the system performance. The effectiveness and favorable performance of the proposed scheme are shown by simulations with H.264 SVC traces of high definition (HD) video clips over MIMO systems.

Available in PDF, EPUB and Kindle. Book excerpt: The Accessible Guide to Modern Wireless Communication for Undergraduates, Graduates, and Practicing Electrical Engineers Wireless communication is a critical discipline of electrical engineering and computer science, yet the concepts have remained elusive for students who are not specialists in the area. This text makes digital communication and receiver algorithms for wireless communication broadly accessible to undergraduates, graduates, and practicing electrical engineers. Notably, the book builds on a signal processing foundation and does not require prior courses on analog or digital communication. Introduction to Wireless Digital Communication establishes the principles of communication, from a digital signal processing perspective, including key mathematical background, transmitter and receiver signal processing algorithms, channel models, and generalizations to multiple antennas. Robert Heath’s “less is more” approach focuses on typical solutions to common problems in wireless engineering. Heath presents digital communication fundamentals from a signal processing perspective, focusing on the complex pulse amplitude modulation approach used in most commercial wireless systems. He describes specific receiver algorithms for implementing wireless communication links, including synchronization, carrier frequency offset estimation, channel estimation, and equalization. While most concepts are presented for systems with single transmit and receive antennas, Heath concludes by extending those concepts to contemporary MIMO systems. To promote learning, each chapter includes previews, bullet-point summaries, examples, and numerous homework problems to help readers test their knowledge. Basics of wireless communication: applications, history, and the central role of signal processing Digital communication essentials: components, channels, distortion, coding/decoding, encryption, and modulation/demodulation Signal processing: linear time invariant systems, probability/random processes, Fourier transforms, derivation of complex baseband signal representation and equivalent channels, and multi-rate signal processing Least-squared estimation techniques that build on the linear algebra typically taught to electrical engineering undergraduates Complex pulse amplitude modulation: symbol mapping, constellations, signal bandwidth, and noise Synchronization, including symbol, frame, and carrier frequency offset Frequency selective channel estimation and equalization MIMO techniques using multiple transmit and/or receive antennas, including SIMO, MISO, and MIMO-OFDM Register your product at informit.com/register for convenient access to downloads, updates, and corrections as they become available.
