COMPARISON OF PTS AND SLM TECHNIQUE IN OFDM SYSTEM

Abstract

Orthogonal Frequency Division Multiplexing (OFDM) system is a multicarrier system use to transfer data at high rate. But it consists a major problem known as Peak to Average Power Ratio (PAPR) which results serious degradation in performance of OFDM system when a non-linear power amplifier is employed in system. The Partial Transmit Sequence (PTS) is one of the most well-known PAPR reduction technique for OFDM system. In this paper, a PTS technique is propose to reduce the high Peak to Average Power Ratio (PAPR). The simulation result shows that our proposed PTS technique, achieves better reduction of PAPR at reduced computational complexity when compared to SLM technique.
