Nowadays, as 3G systems such as WCDMA, CDMA2000 and TD-SCDMA become mature and goes into business, people start to concentrate on the reach of the next generation wireless communication systems. Next generation wireless communication systems are expected to provide high data rate and robust transmission so as to support new applications like high quality multimedia services and high speed data transfer. To meet the demands, we have to increase the operation band and/or increase the spectrum efficiency. Since spectrum is a precious resource in wireless communications, a number of new technologies are developed to enhance the spectrum efficiency such as multiple-input multiple-output(MIMO), cross layer scheduling, orthogonal frequency division multiplexing(OFDM), joint source channel coding(JSCC) etc. Most of these technologies require channel state information at the transmitter (CSIT) to enhance the performance. However, perfect CSIT is hard to obtain in practice. In FDD systems, only a limited number of bits(e.g. 6 bits for WiMAX [1]) can be allocated to carry the CSIT feedback, namely the limited feedback. Moreover, the feedback CSIT may not be error free due to the feedback channel noise. Hence the efficient utilization of the limited feedback bits and the robustness of the feedback design become important. In this Thesis, we focus on the following problems related to the design and analysis of wireless communication systems with limited CSIT feedback: optimal feedback design for MIMO-OFDM systems: We first consider error free limited feedback and propose a systematic design framework for MIMO-OFDM systems on frequency selective channels. We formulate the design problem into the classical vector quantization problem with a modified distortion metric. We find that with a small number of bits for CSIT feedback, there is significant capacity gain in the MIMO-OFD.

Book excerpt: Doctoral Thesis / Dissertation from the year 2023 in the subject Engineering, Indian Institute of Technology, Delhi, language: English, abstract: Over the recent few years, optical wireless communication (OWC) has attracted significant attention in both academia and the research community. Contrary to radio frequency (RF) systems, the spatial confinement of the optical beams makes the OWC system a potential system offering higher data rates and secured communication. OWC systems and applications in several areas, such as terrestrial outdoor (free-space optical (FSO) communication), indoor and outdoor visible light communication (VLC), etc. For the terrestrial outdoor FSO systems, spatial diversity techniques are employed over FSO links to enhance the diversity and overall performance. To this end, the spatial diversity techniques corresponding to the state-of-the-art are repetition coding (RC), transmit laser selection (TLS), and orthogonal space-time block codes. Note that, TLS is the optimal transmission scheme in the FSO systems. In this dissertation, we name the conventional TLS scheme as a single TLS (STLS) scheme. However, the performance of the conventional STLS scheme is highly dependent on the feedback errors. On the other side, the outdoor VLC finds applications in vehicle-to-vehicle (V2V) communications, infrastructure-to-vehicle (I2V) communications, etc. Emphasizing the state-of-the-art corresponding to the outdoor V2V-VLC systems, there is a lack of comprehensive modeling and performance investigation under the adverse challenges of the outdoor VLC environment. Moreover, to address the challenges of the next-generation-based outdoor intelligent transportation systems (ITSs), an indoor testbed design for an outdoor I2V-VLC system is still missing. In order to enhance the diversity and overall performance of the terrestrial outdoor FSO systems, the study begins by proposing two novel TLS schemes. We call the proposed schemes as two TLS (TTLS) and modified error-tolerant weighting scheme (METWS). Note that, the conventional STLS scheme gives optimal performance under a perfect feedback scenario. However, its performance degrades significantly under an imperfect feedback scenario. To this end, the two proposed schemes overcome the practical limitations of the conventional STLS scheme. Moreover, we analyze the performance of the two proposed schemes for both perfect and imperfect channel state information (CSI)-based communication scenarios. Further, different performance metrics, such as bit error rate (BER), diversity gain, etc., are thoroughly analyzed. Furthermore, to gain more insight

Book excerpt: This dissertation studies the communication technologies in relaying systems with multiple antennas, especially in the multiple-input multiple-output (MIMO) two-way relaying systems. Both information-theoretic aspects and practical communication strategies are considered and analyzed. For the information-theoretic analysis, an analytical framework for the coverage of MIMO relaying systems based on an outage capacity criterion is proposed. For MIMO two-way relaying systems, different data combining schemes at the relay are compared based on their achievable rates. In addition, optimal time-division (TD) strategies for MIMO two-way decode-and-forward (DF) relaying systems are proposed and analyzed. When the optimal TD strategies are applied, the increase of the achievable rate regions in the system is significant compared to those using the equal TD strategy. For the practical transmission schemes, we propose the self-interference (SI) aided channel estimation and data detection schemes for the broadcast phase of two-way DF relaying systems. Such schemes exploit the SI in two-way DF relaying systems when the superposition coding (SPC) scheme is applied. When the network coding scheme is applied in two-way DF relaying systems, we propose an asymmetric data rate transmission scheme that utilizes the known data bits at the receivers. Such a scheme exploits the a priori known bits at the weak link receiver in the broadcast phase of two-way relaying systems.

This book was released on 2016 with total page 260 pages. Available in PDF, EPUB and Kindle. Book excerpt: Consumer demand for wireless networks has experienced an exponential increase in recent years, and such trend is expected to continue in the coming years. Therefore, there is a pressing need for more effective communication schemes to be able to cope with the explosive growth in the wireless demand. An important resource which can be very useful in developing more effective communications schemes is channel state information which is available at the transmitters (CSIT). CSIT is usually provided to the transmitters via feedback channels from the receivers. Timely and accurate CSIT has been shown to provide enormous theoretical gains in terms of communication rate. However, in most realistic scenarios, instantaneous and perfect CSIT is not feasible due to physical constraints on the feedback channel. Furthermore, the CSIT supplied by different receivers can often times be of different quality in terms of timeliness and accuracy, which results in networks with heterogeneous/hybrid CSIT. In this dissertation, we provide new tools and techniques to better understand and analyze the fundamental limits of wireless networks under practical CSIT constraints. In particular, we develop mathematical tools that capture the impact of various types of CSIT on the received signal dimensions at different receivers in a wireless network. We also show how the developed tools are used to solve a broad spectrum of problems in network information theory, from interference networks such as X-Channel with delayed CSIT, 3-user Interference Channel with delayed CSIT, Interference Channel with limited transmitter cooperation and delayed CSIT, and 2-by-k multiple-input single-output broadcast channel (MISO BC) with delayed CSIT, to various problems in informationtheoretic security, and finally, MISO BC under heterogeneous CSIT. The developed tools presented in this dissertation provide new insights on the impact of CSIT on the dynamics of wireless networks. Beside the significance of quality of CSIT in wireless networks, quality of service (QoS) requirements by the traffic also play an important role in the design of better communication schemes. The majority of increasing traffic volume over wireless networks is expected to be video, which is in most cases delaysensitive; i.e., packets should be delivered by a certain time, otherwise they will not be useful to the user. Therefore, we study fundamental limits of communicating delay-sensitive traffic over heterogeneous wireless networks, which are emerging structures in modern wireless networks. We provide approximate characterization of the timely throughput capacity of such heterogeneous wireless networks, and develop near-optimal algorithms.

Available in PDF, EPUB and Kindle. Book excerpt: Wireless-powered communication is an emerging technology for powering the large number of miniature devices of the future. In a wireless-powered communication system, low-power sensors extract energy from the incident wireless signals to power their operations such as information transmission, sensing or reception. Due to sporadic energy availability, however, such a system is fundamentally different from a traditionally-powered communication system. This dissertation investigates three distinct aspects of wireless-powered communications to get insights on the system operation. First, leveraging concepts from finite-length information theory, an analytical framework is developed for examining wireless-powered communications with short packets, i.e., in the finite blocklength regime. This is relevant as remotely-powered communications may entail short packets due to small payloads, low-latency requirements, or limited energy to support a longer transmission. Second, using a stochastic geometry framework, an analytical model is developed for characterizing the performance of wireless-powered communications in the millimeter wave (mmWave) band. The proposed model incorporates the key features of mmWave systems such as directional beamforming and sensitivity to building blockages. Finally, the power transfer efficiency and the energy efficiency of a wireless-powered communication system aided by massive MIMO is characterized. The broad goal of this dissertation is to better understand wireless-powered communications in the context of the emerging technologies for 5G.
