Book Description
This thesis investigates detection technologies for multiple-input multiple-output (MIMO) systems and cooperative communications. The exploitation of detection methods and relay strategies to achieve near-optimal performance (measured by symbol error rate or minimum mean squared error) and reductions of the running time of detection methods are the main focus of this thesis. A signal-to-noise ratio (SNR)-dependent radius control sphere detector (SD) algorithm, a general framework of statistical pruning SD, and an improved K-best SD are proposed. These SD algorithms reduce the detection running time in terms of the average number of visited nodes, with negligible performance loss compared with that of optimal maximum likelihood (ML) detection. In order to optimize the MIMO relay performance, an estimate-and-forward (EF) relay strategy is also developed. The emerging trend towards large MIMO and cooperative communication systems makes the development of low running time strategies with near-optimal performance more important. Thus, an EF list generated by SD is also proposed to reduce the number of computational operations for the EF scheme in large MIMO relay networks; this method is called list EF. Overall, the research findings should help to reduce the running time and improve the reliability of detection algorithms, to achieve a desirable trade-off between running time and performance, and to provide efficiently-implementable MIMO and cooperative detection algorithms.

Book Description
Providing an all-encompassing self-contained treatment of Near-Capacity Multi-Functional MIMO Systems , the book starts by categorizing the family of Multiple-Input Multiple-Output (MIMO) schemes as diversity techniques, multiplexing schemes, multiple access arrangements and beam-forming techniques. Sophisticated coherent and low-complexity non-coherent MIMO receivers dispensing with channel estimation are considered in both classic and cooperation-aided scenarios. It is demonstrated that in the presence of correlated shadow-fading, cooperation-assisted systems may be expected to outperform their non-cooperative counterparts. The book contains a 100-page chapter on the unified treatment of all block codes in the context of high-flexibility, cutting-edge irregular Linear Dispersion Codes (LDC), which approach the MIMO-capacity. The majority of the book’s solutions are in the optimum sphere-packing frame-work. Sophisticated amalgam of five year’s near-capacity MIMO research Detailed examination of wireless landscape, including the fields of channel coding, spacetime coding and turbo detection techniques Novel tool of Extrinsic Information Transfer Charts (EXIT) used to address recent developments Material presented logically, allowing advanced readers to turn directly to any specific chapter of interest One of the only books to cover these subjects, giving equal weighting to each

Book Description
Multiple-input multiple-output (MIMO) systems can increase the spectral efficiency in wireless communications. However, the interference becomes the major drawback that leads to high computational complexity at both transmitter and receiver. In particular, the complexity of MIMO receivers can be prohibitively high. As an efficient mathematical tool to devise low complexity approaches that mitigate the interference in MIMO systems, lattice reduction (LR) has been widely studied and employed over the last decade. The co-authors of this book are world's leading experts on MIMO receivers, and here they share the key findings of their research over years. They detail a range of key techniques for receiver design as multiple transmitted and received signals are available. The authors first introduce the principle of signal detection and the LR in mathematical aspects. They then move on to discuss the use of LR in low complexity MIMO receiver design with respect to different aspects, including uncoded MIMO detection, MIMO iterative receivers, receivers in multiuser scenarios, and multicell MIMO systems.
