The focus of the book is the physical layer, and it collects the contributions of many important researchers around the world. So many different works on WiMAX show the great worldwide importance of WiMAX as a wireless broadband access technology. This book is intended for readers interested in the transmission process under WiMAX. All chapters include both theoretical and technical information, which provides an in-depth review of the most recent advances in the field, for engineers and researchers, and other readers interested in WiMAX. In the first section, Advanced Transmission Techniques, readers will find chapters on modern antennas design for future WiMAX communications and the transmission enhancements achieved by space-time coding. In the second section, Physical Layer Models, there are several chapters on the Automatic Repeat Request process and the common Peak to Average Power Ratio problem for OFDM modulation. Finally, in the third section the reader will find chapters related to mobile WiMAX problems, handover processes and interaction with other technologies. Prof. Roberto C. Hincapie & Prof. Javier E.
