Book Synopsis Performance Analysis and Design of Space-time Codes by : Chen Liao

Available in PDF, EPUB and Kindle. Book excerpt: Wireless communication technologies have evolved from the original analog networks to IP-based network. Today's wireless communications have been affected by increasing customer expectations on wireless wideband internet services and continuously evolving improvements on technologies. Wireless communication systems must increase their ability to respond to the challenges. The new generation wireless systems (3G/4G) are designed for this purpose. The notable characteristic of 3G/4G is that it provides high data rate transmission at data rate up to 348kbps/2Mbps for 3G and 100Mbps/1Gbps for 4G. Designing the system for such high data rate transmission has become very challenging for wireless systems where the multipath fading is an important factor. In recent years, researches are ongoing in the industry and academic to increase capacity performance of wireless systems through antenna diversity. Multiple Input Multiple Output (MIMO) is one of the major recent developments in the study of high data rate transmission. There has been considerable attention paid to remarkable performance improvements in MIMO in terms of capacity. Another technology that has been traditionally adopted for wireless communications is the channel coding. Combining MIMO with channel coding has received increasing interest to support a variety of high data rate applications. These schemes have been termed as "space-time codes". Space-time codes are currently an area of exciting activity and have been studied as promising candidates for future 3G/4G systems. The most important characteristic of space-time codes is that it can provide full diversity gain as well as coding gain. In this dissertation, both performance analysis of upper bound of Pair-Wise Error Probability (PEP) and exact PEP are performed. In the derivation of exact PEP, a new method is presented. The method is straightforward and comprehensible. The upper bound provides the insight to understand the performance behavior for high Signal-to-Noise Ratio (SNR), while the exact PEP provides a better understanding of the performance behavior to other range of SNR. Design criteria for space-time codes had been first developed by Tarokh, which utilize the analysis of the upper bound on PEP to maximize diversity gain and coding gain from the property of the codeword distance matrix. These criteria are the most widely accepted, which form the basis for space-time codes. The criteria assume that the performance of space-time codes is dominated by the dominant error events. However, there are no dominant error events in fading channel for space-time codes. Therefore, Tarokh's criteria do not provide design guideline for the coding gain. Union bound analysis offers a alternative solution to this problem. The union bound technique is a more attractive method that allows us to analyze the contribution of all error events to the performance. In this thesis, the performance of space-time codes are analyzed using union bound analysis. Based on the union bound on Frame Error Rate (FER), new design criteria are proposed. This is achieved by applying more accurate upper bound of PEP in the union bound analysis. With the proposed criteria, new coding gain performance metrics had been defined. New codes based on the new performance metrics are designed and their coding gain performance superiority are demonstrated. Space-time block codes have been initially designed to provide full diversity order with low decoding complexity, but without coding gain. By integrating space-time trellis codes with space-time block codes, super-orthogonal space-time trellis codes can significantly enhance the coding gain performance. However, the super-orthogonal space-time trellis codes improve performance only in slow fading channel, but do not perform well in fast fading channel. In fast fading channel, the orthogonal design of space-time block codes has little effect on the coding gain and does not lead to noticeable improvement. Furthermore, super-orthogonal space-time trellis codes introduce the diversity gain loss in fast fading channel. It is well known that the performances of space-time codes are dominated by diversity gain and any diversity gain loss may cause substantial loss in performance. We therefore develop orthogonal space-time trellis codes, which improve performance in diversity gain in fast fading channel. The improvement is achieved by transferring the vector output of space-time trellis codes into an orthogonal matrix of space-time block codes, and meanwhile maintaining the symbol Hamming distance of space-time trellis codes. Theoretical analysis and simulation results had demonstrated that the proposed codes can improve diversity gain linearly with an increase in the number of transmit antennas. Performance saturation and decoding complexity increase with the increased number of trellis states are the major problems that trellis-based codes have to face in practice. Turbo codes that allow for reaching near Shannon limit performance are a significant advance in digital communications. Space-time turbo codes have been developed to achieve high performance. In a perfect world, system designers would like to achieve high performance while maintaining a full code rate. Therefore, puncture operation is always used in space-time turbo codes. The problem with the puncture operation in space-time turbo codes is that codeword distance matrix is rank deficient for small diversity gain in slow fading channel, which constitutes a major problem with space-time turbo codes. Space-time turbo codes that concern the rank deficiency have been developed. The codes improve performance by reducing the effect of rank deficiency on performance, but exist high complexity in both code structure and design criteria. This limitation makes the codes not suitable for the design of complex codes with large trellis state and/or large numbers of transmit antennas. A new space-time turbo codes have been proposed in this research. In previous works, it has been demonstrated the systematic structure with the rotation of the output of the low constitute encoder can effectively reduce the rank deficient effect on performance. Our new codes utilize the systematic characteristic to construct a simple code structure. Further, a simple but very effective trace criterion has been proposed. With the simple codes structure and design criteria, the design of complex codes can be achieved with significant improvement in coding gain performance for the systems with small diversity gain in slow fading channel. Overall, this dissertation presents new design criteria and new codes that contribute to improving performances of space-time codes.

Book Synopsis The Error Performance of Space-time Codes Over MIMO Millimeter-wave Channels by : Ahmed Aboutaleb
Download or read book The Error Performance of Space-time Codes Over MIMO Millimeter-wave Channels written by Ahmed Aboutaleb and published by . This book was released on 2018 with total page 92 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this thesis, the error performance limits of millimeter-wave (mm-wave) communication systems are considered. To derive such performance limits, an accurate statistical channel model must be developed. We argue that the Nakagami-m distribution accurately models the statistics of small-scale fading at mm-wave frequencies and provide extensive numerical simulations for the indoor environment at 60 GHz. Then, we derive an upper bound on the error performance of any space-time coding scheme that well-describes the diversity and coding gains. Our upper bound is based on the pairwise error probability. We then examine the resulting diversity and coding gains to propose design criteria that maximize the diversity and coding gains. Orthogonal space-time block codes are shown to achieve the maximum diversity gain but not the maximum coding gain. Indeed, we show that there exists a trade-off between the diversity gain and the coding gain. Furthermore, we investigate the effect of blockage on the error performance using stochastic geometry. Our analysis and simulations show that blockage only reduces the coding gain and does not affect the diversity gain. This reduction in the coding gain is a function of the probability of line-of-sight communication, path loss exponents, the distance between transceivers, and the coding gain without considering the effect of blockage. For instance, in a typical indoor environment for mm-wave communication, blockage due to humans or other obstacles can reduce the coding gain by up to 1.5 dB for a bit error probability of 10−3.

This book was released on 2007 with total page 268 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this thesis, issues such as link adaptation that include adaptive spatial mode in the context of orthogonal frequency division multiplexing (OFDM) is addressed, particularly in a multiple-input single-input (MISO) configuration suitable for mobile communications. The performances of ST- and SF-OFDM incorporating channel coding are extensively investigated in the presence of channel fading and noise. Realizing that ST and SF behave differently in different enviroments, a new adaptive spatial mode (ASM)-OFDM is proposed. This scheme selects the mode of transmission based on the instantenous signal noise ratio (SNR) for a 2 x 1 MISO system. A new adaptive multiple antenna selection (AdMAS) using second-order moment of the channel impulse response between multiple transmitting antennas and a single receiver MISO-OFDM configuration os also proposed a major contributio. This scheme employs a 4 x 1 space-time-frequency coding with a symbol rate of 3/4, using orthogonal signals, to avoid high complexity in detection. In the proposed AdMAS scheme the worst faded channel(s) in (are) adaptively turned off based on the calculated second-order moment of the channel impulse response. Findings show that the proposed scheme outperforms other multiple antenna schemes such as the one based on the mean of the channel impulse response, especially at higher order modulation. Throughout the simulation, channel state information (CSI) is assumed to be known both by the transmitter and the receiver which may be achieved via a dedicated feedback channel or through the reciprocity of the channel such as that found in time division duplex (TDD) system. Minor contribution of this thesis includes a simplified sphere decoding algorithm for MIMO that forms part of the detection scheme at the receiver. A maximum achievable diversity order of the 4 x 1 MISO-OFDM has also been derived analytically and proved through simulation. A diversity gain of more than 10 dB can be achieved with Binary Phase Shift Keying modulation when compared to Almouti's Space-Time Block Code (STBC) at a bit error rate (BER) of 10-3. This makes the proposed scheme a potential scheme to be considered for the future high data rate communication. The proposed schemes are tested through simulations in different types of practical channels such as Wireless Local Area Network (WLAN) IEEE 802.11, Rayleigh fading with various delay spreads, as well as the most recent Fixed Broadband Wireless Access (FBWA) IEEE 802.16 Standford University Interim Channels, or better known as the WiMAX channels.

This book was released on 2005 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Mobile communication technologies have grown significantly in recent years. In order to satisfy the increasing number of users and their ever increasing requirements, there have been continuous enhancements in present-day wireless standards. With the proliferation of these standards, use of conventional techniques for improving receiver performance becomes very complex. Hence, the design and analysis of low complexity suboptimal techniques, which are comparable to optimal techniques on performance basis and consume less power, has received tremendous interest in a research community. Along these lines this thesis analyzes a suboptimal diversity combining system called generalized selection combining (GSC). In this thesis, we develop an analytical framework for error rate analysis of the GSC technique in a correlated Nakagami fading environment. We derive the moment generating function of the output SNR of a GSC system and, using the moment generating function, the bit error rate of the system is derived. We show that our developed analytical expressions converge to the results presented in literature for the special cases of independent identically distributed GSC with Rayleigh and Nakagami fading, and maximal ratio combining with IID Nakagami fading. Finally, the analytical equations are plotted, verified and compared with the results from system simulations.

"Space-Time Block Coding for Multiple Antenna Systems" is devoted to space-time coding, a MIMO transmit strategy which exploits transmit diversity and high reliability systems. The concept of space- time coding is explained in a systematic way including simulation examples. The book includes algorithm design and detailed performance study of space-time codes for multiple-antenna systems with and without channel state information at the transmitter. This valuable resource will appeal to graduate and postgraduate students, researchers and engineers involved in design and implementation of STC for MIMO systems.
