An Improved DSI-PTS for PAPR Reduction of OFDM System

چکیده
Peak-toaverage power ratio (PAPR) is one of the major problems of orthogonal frequency division multiplexing (OFDM). The larger PAPR signal may cause high out-of-band radiation, when the OFDM signal is passed through a radio frequency power amplifier. In literatures, many researchers proposed various methods to reduce PAPR. Among those, Dummy sequence Insertion (DSI) and partial transmit sequence (PTS) are well-known PAPR reduction techniques for OFDM signals,however, it results a huge amount of computation complexity.This paper proposes an improved DSI-PTS scheme that is able to carry out improved PAPR performance with lesser system complexity than the conventional methods. In addition to that, this scheme requires no side information.
