A Multi-probabilistic Based PTS Technique to Reduce PAPR in an OFDM System
Abstract Orthogonal Frequency Division Multiplexing (OFDM) is a Multi-carrier Modulation technique which is used for high data rate transmission as it reduces the effect which occurs due to frequency- selective fading channels. Peak to Average Power Ratio (PAPR) is one of the major issue with OFDM. The approaches to obtain minimization of PAPR in an OFDM signals has brought much interest among the researches in recent days. OFDM has higher PAPR when compared to single carrier modulation techniques because OFDM signal is the combination of multiple narrow band signals which leads to higher PAPR and abnormally effects the complexity of power amplifiers. In this paper the simulations show that compared to traditional Selective Mapping (SLM) technique the Partial Transmit sequence (PTS) technique achieves much better minimization in PAPR. Complementary Cumulative Distributive Function (CCDF) is used as a metric to calculate PAPR.
