Book Description
One of the main issues of wireless communication systems is to cope with random variationof their channel conditions. In many wireless communication systems, the receiver estimatesthe channel for symbol detection. It is usually assumed that channel estimation is perfect,but in practice, channel estimation error (CEE) can become signicant and can degrade theperformance of wireless communication systems. This thesis addresses the eects of channelestimation error in two contexts: CEE in cooperative communication systems and CEE inlink layer performance.Cooperative diversity, which has been recently presented as an eective way of mitigatingthe eect of deep fades in wireless channels and improving spectral and power eciencyof the wireless networks, is considered in the rst part of this dissertation. Taking intoconsideration the presence of CEE, part I of this thesis analyzes a few cooperative communicationsystem models, which display dierent levels of practicality and represent largeclasses of cooperative systems in the literature. This thesis spells out delineating aspectsof these models and rigorously compares their error probabilities. Furthermore, a novelsignal detection scheme in the presence of CEE is presented for large classes of cooperativecommunication systems.Part II of this dissertation focuses on cross layer issues between the physical and linklayers of wireless communication systems. In particular, the frame error probability (FEP)is derived for a wireless communication system over fading channels in the presence ofCEE. Part II also explores the issue of optimizing bit transmission power for minimizing theexpected energy required to reliably deliver a frame to the destination node through an ARQmechanism over a fading channel. Also, an optimization algorithm is designed to minimizethe expected energy for reliable delivery of a frame for the systems under consideration.

Book Description
The four short years since Digital Communication over Fading Channels became an instant classic have seen a virtual explosion of significant new work on the subject, both by the authors and by numerous researchers around the world. Foremost among these is a great deal of progress in the area of transmit diversity and space-time coding and the associated multiple input-multiple output (MIMO) channel. This new edition gathers these and other results, previously scattered throughout numerous publications, into a single convenient and informative volume. Like its predecessor, this Second Edition discusses in detail coherent and noncoherent communication systems as well as a large variety of fading channel models typical of communication links found in the real world. Coverage includes single- and multichannel reception and, in the case of the latter, a large variety of diversity types. The moment generating function (MGF)-based approach for performance analysis, introduced by the authors in the first edition and referred to in literally hundreds of publications, still represents the backbone of the book's presentation. Important features of this new edition include: * An all-new, comprehensive chapter on transmit diversity, space-time coding, and the MIMO channel, focusing on performance evaluation * Coverage of new and improved diversity schemes * Performance analyses of previously known schemes in new and different fading scenarios * A new chapter on the outage probability of cellular mobile radio systems * A new chapter on the capacity of fading channels * And much more Digital Communication over Fading Channels, Second Edition is an indispensable resource for graduate students, researchers investigating these systems, and practicing engineers responsible for evaluating their performance.

Book Description
A unified presentation, broad coverage, single-volume convenience This timesaving reference provides a unified approach to the performance analysis of digital communication systems over generalized fading channels. Employing alternative forms of such classical mathematical functions as the Gaussian Q-function, the Marcum Q-function, and the incomplete Gamma function, the book expresses communication system error probability performance in terms of the moment generation function (MGF) of the fading process. This MGF-based approach provides the unifying backbone of the book. Digital Communication over Fading Channels discusses in detail coherent, differentially coherent, and noncoherent communication systems as well as a large variety of fading channel models typical of communication links found in the real world. Coverage also includes single- and multichannel reception and, in the case of the latter, a large variety of diversity types. For each combination of communication type, channel fading model, and diversity type, the average bit error rate and/or symbol error rate is expressed in an easy-to-evaluate form. Special features include: * Important results previously scattered over many publications-now in a single volume * Simplified results heretofore available only in complex forms * Extremely broad coverage of topics * Explores practical applications, including the problem of optimum combining in the presence of co-channel interference

Book Description
"In modern and future cellular networks such as Long-Term Evolution-Advanced (LTE-A)and 5G systems, cooperative communication can be deployed as an efficient method to improvesystem performance and meet the high-speed data transmission needs of multimediaservices. This thesis studies cooperation in the multiple access channel (MAC) setting,which includes the relay channel (RC) setting as a special case. These cooperative settingsapply to uplink transmission in cellular networks and form the basis to improve the widenetwork performance.The thesis proposes a time-division half-duplex scheme for the MAC with transmittercooperation (MAC-TC). The proposed scheme divides each transmission frame into threephases with variable durations. The two user equipments (UEs) partially exchange theirinformation in the first two phases, then cooperatively and coherently transmit to the basestation (BS) in the third phase, i.e., each UE performs a partial decode-forward (pDF) ofthe other UE information. The BS then performs joint decoding using the signals receivedin all three phases. After designing the scheme for the discrete memoryless channel (DMC),the thesis applies it to the Gaussian channel, derives its optimal resource allocations formaximum throughput and studies the outage performance over fading links. Comparedwith existing schemes, the proposed scheme improves throughput and outage performance,which makes it appealing for deployment in future cellular networks by utilizing the device-to-device (D2D) and infrastructure modes in the uplink transmission.The proposed scheme is near capacity-achieving when the cooperative links are strongerthan the direct links. Compared to existing schemes, this scheme achieves the same orbetter spectral efficiency with simpler signals and shorter decoding delay. By analyzingthe KKT optimality conditions for the maximum transmission rate, the thesis shows thatas the inter-user link qualities increase, the optimal scheme moves from no cooperation topartial then to full cooperation, in which the users fully exchange their information. Theoptimal power allocation to achieve the maximum throughput is analytically derived.The thesis further formulates the outage probability of the cooperative scheme overRayleigh fading channels assuming full channel state information (CSI) at receivers andlimited CSI at transmitters. Results show that cooperation can significantly reduce outageprobabilities and achieve the full diversity order despite additional outages at the UEs. Thethesis considers the RC setting in detail and analytically derives the outage performance for the coherent pDF relaying. Results show that the proposed scheme outperforms the existingschemes since it employs coherent transmission and joint decoding at the destination.Last, the thesis proposes a MAC with a joint source-destination cooperation (MAC-SDC)scheme that also engages the BS in cooperation by employing quantize-forward relaying.In this scheme, the users exchange their information not only through the cooperativelinks as in the MAC-TC, but also via the feedback links from the BS. Results showachievability improvement especially when the cooperative links are marginally strongerthan direct links. Moreover, for the RC setting, the thesis proves that the proposed schemeasymptotically achieves capacity by reaching the cutset bound as BS power increases." --
