This book was released on 2006-07-10 with total page 282 pages. Available in PDF, EPUB and Kindle. Book excerpt: Coordinated Multiuser Communications provides for the first time a unified treatment of multiuser detection and multiuser decoding in a single volume. Many communications systems, such as cellular mobile radio and wireless local area networks, are subject to multiple-access interference, caused by a multitude of users sharing a common transmission medium. The performance of receiver systems in such cases can be greatly improved by the application of joint detection and decoding methods. Multiuser detection and decoding not only improve system reliability and capacity, they also simplify the problem of resource allocation. Coordinated Multiuser Communications provides the reader with tools for the design and analysis of joint detection and joint decoding methods. These methods are developed within a unified framework of linear multiple-access channels, which includes code-division multiple-access, multiple antenna channels and orthogonal frequency division multiple access. Emphasis is placed on practical implementation aspects and modern iterative processing techniques for systems both with, and without integrated error control coding. Focusing on the theory and practice of unifying accessing and transmission aspects of communications, this book is a valuable reference for students, researchers and practicing engineers.

Available in PDF, EPUB and Kindle. Book excerpt: Next generation wireless systems will use multiple antenna technologies, also known as multiple-input multiple-output (MIMO), to provide high data rates and robustness against fading. MIMO communication strategies for single user communication systems and their practical application in wireless networks are by now well known. MIMO communication systems, however, can benefit from multiuser processing by coordinating the transmissions to multiple users simultaneously. For numerous reasons, work on the theory of multiuser MIMO communication has yet to see broad adoption in wireless communication standards. For example, global knowledge of channel state information is often required. Such an unrealistic assumption, however, makes it difficult in practice to implement precoding techniques. Furthermore, the achievable rates of the conventional multiuser MIMO techniques are far from the theoretical performance bounds. These and other factors motivate research on practical multiuser communication strategies for the MIMO broadcast channel (point to multi-point communication) and the analysis of those strategies. The primary contributions of this dissertation are i) the development of four novel low complexity coordinated MIMO transceiver design techniques to approach the theoretical performance bound and ii) the investigation of the optimality of the proposed coordinated wireless MIMO networks. Several coordinated beamforming algorithms are proposed, where each mobile station uses quantized combining vectors or each base station uses limited feedback from the MS. The asymptotic optimality of the proposed coordinated beamforming system for the MIMO Gaussian broadcast channel is next investigated. For multi-stream transmission, a novel block diagonalized vector perturbation is proposed and the achievable sum rate upper bound of the proposed system is derived. Finally, for multi-cell environments, linear and non-linear network CBF algorithms supporting multiple cell-boundary users are proposed. The optimality of network coordinated beamforming in terms of the number of receive antennas is also investigated.

Download or read book Efficiency and Security Analysis in Multi user Wireless Communication Systems written by Jie Gao and published by . This book was released on 2014 with total page 153 pages. Available in PDF, EPUB and Kindle. Book excerpt: Efficiency and security are major concerns with increasingly higher importance in modern wireless communications. These two concerns are especially significant for multi-user wireless communications where different users share or compete for resources. Among different users, there are possibilities of cooperation, competition, and/or malicious behavior. Due to the possibility of cooperation among the users, the spectral and energy efficiency in multi-user wireless communications could be boosted. Due to the possibility of competition, the resource allocation in multi-user wireless systems may reach certain equilibrium. Due to the possibility of malicious behavior, the security and reliability of wireless communications can be undermined. In this thesis, a comprehensive analysis on the issues of efficiency and security in multi-user wireless communications is developed for three systems in four scenarios. The first multi-user system of multiple-input multiple-output two-way relaying has the feature of cooperation including a limited coordination scenario and a full coordination scenario. It is shown that high spectral efficiency can be achieved with efficient energy consumption in this system due to the cooperation among the users. Moreover, full coordination yields better results in both spectral and energy efficiency than limited coordination at the cost of higher overhead. The second multi-user system of legitimate transceiver(s) with a jammer features the existence of malicious behavior. To measure the jamming threat, the worst-case jamming is studied for different cases according to the jammer's knowledge of the legitimate communication. The optimal/sub-optimal jamming strategy in each case is analyzed and derived. The third multi-user system of two-user interference channel features the competition of the users. The situation is modeled using noncooperative games with continuous mixed strategies. The outcomes of the games are analyzed through the establishment of the conditions for the existence and uniqueness of mixed strategy Nash equilibrium.
