The book "Adaptive MIMO Systems" by Peerapong Uthansakul provides a comprehensive examination of MIMO (Multiple Input Multiple Output) systems in non-i.i.d. (identically and independently distributed) channels, which are typically encountered indoors. It addresses the challenges arising from the specific characteristics of these environments and develops adaptive MIMO systems to optimize transmission rates. The channel models presented are based on real measurement data, providing a solid foundation for analysis. The book also covers important aspects such as signal normalization, mutual coupling, and the effects of amplifiers to evaluate MIMO capacity. Additionally, practical performance metrics such as Bit Error Rate (BER), computational complexity, and processing delay are analyzed. This work is aimed at MIMO designers and researchers in both academic and industrial research, offering valuable insights into the practical challenges and solutions in the field of MIMO technology.
