PAPR Reduction Techniques for OFDM Signals

Orthogonal Frequency Division Multiplexing (OFDM), a multicarrier modulation technique, widely used for many of the latest wireless standards such as Wi-Fi, LTE / LTE-A, DAB, DVB, WiMAX and so on. However, its high peak-to-average power ratio (PAPR) for a large number of subcarriers which may drive the amplifier into non-linear region that radiates signals out of band, making it unobtrusive for practical applications. In this book, the comprehensive research and comparison are put forward for a variety of currently promising PAPR reduction methods on the basis of extensive reading and studying of associated papers and literature in this research area. The book caters to the needs of research fraternity and students in the field of wireless communication. The requirement for the readers of this book is to be familiar with the basics of OFDM system, however, R & D engineers from industry community working under wireless communication group can also benefit from this book as a supplementary reference.
