Subdivided into six major thematic parts, this book provides profound insight into power-line MIMO channel and noise aspects in Part I and Part II respectively. Building on this foundation and taking into account electromagnetic compatibility (EMC) aspects in Part III, Part IV describes MIMO and multi-user strategies in use in currently deployed systems. Part V then looks at advanced options of MIMO and multi-user processing technologies, drawing from a wide variety of research areas such as linear and nonlinear signal processing, space-time-coding, convex optimization, scheduling, and game theory. The book is rounded off by Part VI on case studies and field trials, where the advanced technologies of tomorrow are put into practice today.
