One of the promising solutions to the challenges of future communication systems is to design efficient coding systems over time, space and frequency domain for MIMO-OFDM systems. In this book, comprehensive review of coding over time, space and frequency domain for MIMO-OFDM system is presented. New and efficient space-time codes over MIMO-OFDM systems are proposed with their concatenated version employing iterative decoding. The review of various space-time coded OFDM systems and the proposed space-time codes for MIMO-OFDM presented in this book should be of great interest to students at undergraduate and postgraduate class in the field of telecommunication Engineering. This book will also be useful for professional Engineers in the field of communication engineering in designing new wireless communication systems.
