This book is a journey to the cutting edge of research in the field of wireless telecommunications. Many other books take you on a similar but altogether different journeys: books on space-time coding, turbo-coding, OFDM, and the like. Our work takes the best of what is out there today, looks at where the wireless world wants to go, and then advances the best of the current work to reach those future goals. For this reason, my co-authors and I believe this book will take you for the ride of your life.
