Vázquez Araújo, José A. García-Naya, Miguel González-López, Luis Castedo and Javier Garcia-Frias Chapter 19 Chapter 20 Chapter 21 Chapter 22 Pref ac e In recent years, it was realized that the Multiple Input Multiple Output (MIMO) com- munication systems seems to be inevitable in accelerated evolution of high data rates applications. The MIMO systems, have received considerable a ention of researchers and commercial companies due to their potential to dramatically increase the spectral effi ciency and simultaneously sending individual information to the corresponding users in wireless systems. Today, the main question is how to include multiple antennas at transmi er and receiver side and, what are the appropriate methods of detection and signal processing strategies for specifi c applications? This book, intends to provide highlights of the current research topics in the fi eld of MIMO system, to off er a snapshot of the recent advances in this area. This work is mainly destined to cover an overview of the major issues faced today by researchers in the MIMO related areas. Also, it is accessible to anyone with a scientifi c background desiring to have an up-to-date overview of this domain. The book is wri en by specialists working in universities and research centers all over the world to cover the fundamental principles and main advanced topics on high data rates wireless communications systems over MIMO channels. Various aspects of the- ses systems are deeply discussed by emphasis of their recent applications in fi ve part and twenty-two chapters. Moreover, the book has the advantage of providing a collec- tion of applications that are completely independent and self-contained; thus, the in- terested reader can choose any chapter and skip to another without losing continuity. Each chapter provides a comprehensive survey of the subject area and terminates with a rich list of references to provide an in-depth coverage of the application at hand. The fi ve parts of the book is managed as follows: Part 1 Introduction, Detection and Channel Estimation Strategies The fi rst part contains four chapters that investigate an introduction to MIMO systems models together with discussion about diversity, beam forming and, space time cod- ing. The geometrical decoding in MIMO channels by name of la ice decoding, and other type of decoding such as: LS, LMMSE, ML, MAP and joint LSML are considered, too. Finally, the mathematical semi-deterministic MIMO channel model based on elec- tromagnetic sca ering and refl ecting is developed and discussed in details. Part 2 Information Theory Aspects Part2 focus on information theory aspects of MIMO systems, including diversity-gain of MIMO systems, which highlight the trade-off between capacity and bandwidth X Preface effi ciency and rate adaptive source encoding, where the rate is adapted to follow the slow variations of the MIMO channel. Then, the capacity of MIMO system is investi- gated in the presence of both co-channel interference and spatial correlation. Finally, theoretical analysis for both ergodic and outage capacities of downlink transmission together with capacity analysis of uplink cellular MIMO systems by considering the co-channel interference as well as the eff ect of transmit power control are presented. Part 3 Pre-processing and Post-processing in MIMO Systems The non-linear precoder by name of Tomlinson-Harashima Precoder and beamfom- ing are the main core of this part. At fi rst, the capacity of MIMO- THP in perfect and non-perfect CSI is obtained. In continue the conventional THP design is developed for imperfect, correlated and channel estimator error as robust, improved and joint opti- mization, respectively. Joint THP transceiver design for the multi-user MIMO down- link system under both perfect and imperfect CSI is developed, too. Iterative optimi- zation algorithm to determination of transmit and receive beam forming weights for eigen-beam SDM in multi-user MIMO systems is discussed under constraint of both total transmit power and the maximum transmit power. The recent advance in beam forming based on fi nite-rate feedback from a communication-theoretic prespective is addressed as ideal and non-ideal factors of feedback link. Finally, the problem of sym- bol detection in Multi-Device STBC-MIMO systems is addressed. So, two evolutionary optimization methods by names, Biogeography-Based Optimization and Estimation of Distribution Algorithm are proposed to solve the problem of detection in a MD-STBC- MIMO system. Part 4 Application and Case Studies This part contain some advanced application of MIMO systems and some main notes in their implementations, which started by MIMO-OFDM technique that investigate the eff ects of phase noise in centralized and distributed narrowband MIMO systems, and discuss the feasibility of phase and frequency synchronization problem. In con- tinue a novel threshold list subset detector that extends the List subset detector for an iterative turbo-MIMO system is considered. Then, a narrowband interference suppres- sion technique is discussed in MIMO systems. This part terminates with fundamentals for pragmatic MIMO performance evaluation which consider some important notes in implementation from antenna and propagation perspectives. Part 5 Implementation and Experimental Evaluation This part starts with some practical methods for capacity measurement and hardware implementation of MIMO system with QPSK modulation. The implementation of the MIMO system together with sphere decoding and space time coding is discussed, es- pecially with emphasis on wireless sensor network perspective. The above hardware implementation and practical measurement of MIMO system emphasis their potential of dramatically increase of spectral effi ciency and their bo lenecks where should be considered in practice. Finally, the editor would like to thank all the authors for their excellent contributions in the diff erent areas of MIMO systems and hopes that this book will be of valuable help to the readers. H.
