However it suffers from nonlinear error problem, popularly known as high Peak to Average Power Ratio (PAPR) due to nonlinear transfer function of Power Amplifiers in Transmitters. It causes severe performance degradation to the systems that employ link adaptation for achieving better efficiency such as LTE and WiMAX. Therefore it is important to understand the nature and impact of the error. This book will discuss basics of OFDM and provide an in depth understanding of the nonlinear error and its impact of link adaptive OFDM systems. It also provides detail simulation results and analysis of its impact on the system for different channel condition, modulation and FEC coding rate. Finally a compensation technique will be introduced to overcome the impact of nonlinear errors.

Initially the focus of the wireless system was to enable voice communication and therefore data rate requirement was quite low. With the emergence of mobile multimedia service based on 3G and beyond technologies, there is a tremendous growth in demand of wireless services that contains more than just voice data [1][2].

Studies suggest that this high data rate demand is chiefly generated from indoor environments [1], where radio coverage is generally poor due to wall penetration losses inside buildings. The problem is compounded in the cell-edge area which is furthest from the serving macrocell base stations (BS). The ...
