This SpringerBrief discusses the current research on coordinated multipoint transmission/reception (CoMP) in wireless multi-cell systems. This book analyzes the structure of the CoMP precoders and the message exchange mechanism in the CoMP system in order to reveal the advantage of CoMP. Topics include interference management in wireless cellular networks, joint signal processing, interference coordination, uplink and downlink precoding and system models. After an exploration of the motivations and concepts of CoMP, the authors present the architectures of a CoMP system. Practical implementation and operational challenges of CoMP are discussed in detail. Also included is a review of CoMP architectures and deployment scenarios in the LTE-Advanced standard. Readers are exposed to the latest multiuser precoding designs for the CoMP system under two operating modes, interference aware and interference coordination. Wireless Coordinated Multi cell Systems: Architectures and Precoding Designs is a concise and approachable tool for researchers, professionals and advanced-level students interested in wireless communications and networks.

The use of multiple antennas at base stations is a key component in the design of cellular communication systems that can meet high-capacity demands in the downlink. Under ideal conditions, the gain of employing multiple antennas is well-recognized : the data throughput increases linearly with the number of transmit antennas if the spatial dimension is utilized to serve many users in parallel. The practical performance of multi-cell systems is, however, limited by a variety of nonidealities, such as insufficient channel knowledge, high computational complexity, heterogeneous user conditions, limited backhaul capacity, transceiver impairments, and the constrained level of coordination between base stations.

The objectives of this work are as follows to modify and develop new mathematical models of the MVDR algorithm to increase the robustness of MVDR beamformer against steering vector errors caused by calibration or manufacturing errors, and increase the estimation and beamforming accuracy using the actual data mode subjected to double constraints; to design a novel CoMP architecture through innovative division of an LTE cell into three spatial regions, where different scheduling methods (AJN, SCBF, and Non-CoMP) can run in parallel, thus dramatically increasing the capacity of the system; to incorporate MVDR beamformer into CoMP architecture in order to generate accurate beamforming weight within each base station, resulting in reducing signalling overhead among the LTE base stations.

In addition, this research brings new perspectives and understanding to the CoMP system where the interactions among the coordinated BSs are characterized under two operating modes: interference aware (IA) and interference coordination (IC).Under the IA mode, the multicell system is said to be in competition where each BS selfishly adapts its precoding strategies accordingly to the ICI. Naturally, the IA mode represents a strategic noncooperative game (SNG) with the BSs being the rational players, who try to maximize a certain utility for their connected MSs. This work characterizes the SNG played among the BSs by examining the existence and uniqueness of a stable operating point of the system, which is corresponding to a Nash equilibrium (NE) of the multicell game.

This book is unique in presenting channels, techniques and standards for the next generation of MIMO wireless networks. Through a unified framework, it emphasizes how propagation mechanisms impact the system performance under realistic power constraints. Combining a solid mathematical analysis with a physical and intuitive approach to space-time signal processing, the book progressively derives innovative designs for space-time coding and precoding as well as multi-user and multi-cell techniques, taking into consideration that MIMO channels are often far from ideal.Reflecting developments since the first edition was published, this book has been thoroughly revised, and now includes new sections and five new chapters, respectively dealing with receiver design, multi-user MIMO, multi-cell MIMO, MIMO implementation in standards, and MIMO system-level evaluation. Extended introduction to multi-dimensional propagation, including polarization aspects Detailed and comparative description of physical models and analytical representations of single- and multi-link MIMO channels, covering the latest standardized models Thorough overview of space-time coding techniques, covering both classical and more recent schemes under information theory and error probability perspectives Intuitive illustration of how real-world propagation affects the capacity and the error performance of MIMO transmission schemes Detailed information theoretic analysis of multiple access, broadcast and interference channels In-depth presentation of multi-user diversity, resource allocation and (non-)linear MU-MIMO precoding techniques with perfect and imperfect channel knowledge Extensive coverage of cooperative multi-cell MIMO-OFDMA networks, including network resource allocation optimization, coordinated scheduling, beamforming and power control, interference alignment, joint processing, massive and network MIMO Applications of MIMO and Coordinated Multi-Point (CoMP) in LTE, LTE-A and WiMAX Theoretical derivations and results contrasted with practical system level evaluations highlighting the performance of single- and multi-cell MIMO techniques in realistic deployments

This SpringerBrief presents interference coordination techniques for future 5G cellular networks. Starting with an overview of existing interference management techniques, it focuses on practical interference coordination schemes based on beamforming and user scheduling. The proposed schemes aim to deal with the inter-cell interference in multi-cell MIMO networks, cross-tier interference in device-to-device communications underlaying cellular network, and inter-network interference in cognitive radio networks. The performances of the proposed schemes are evaluated both analytically and numerically in terms of several performance parameters, including the sum rate, multiplexing gain, and outage probability of the networks. The results show that the proposed schemes can significantly reduce the effect of interference and improve the quality of service of the networks. Interference Coordination for 5G Cellular Networks is suitable for researchers and advanced students interested in interference coordination or 5G cellular networks.
