Performance analysis of PAPR reduction in OFDM using combined approach method

Abstract

Orthogonal Frequency Division Multiplexing (OFDM) is a multi carrier system which plays an important role in wireless communication system with limitation of soaring Peak to Average Power Ratio (PAPR), compared with single carrier systems. In this proposed method for enhanced performance of PAPR, the combination of Selective Mapping (SLM), Partial Transmit Sequence (PTS) and Dummy Signal Insertion (DSI) is implemented for diverse candidate signals.
