Comparison of peak to average power reduction techniques in OFDM

OFDM (Orthogonal Frequency Division Multiplexing) is generally preferred for high data rate transmission in digital communication. OFDM system has a major shortcoming of high peak to average power ratio (PAPR) value. This paper explains different PAPR reduction techniques and presents a comparison of the various techniques based on theoretical and simulated results. It also presents a survey of the various PAPR reduction techniques and the state of the art in this area.
