Abstract

The high data rate transmission is the today's most demanding parameter hence one of the popular technique used in the communication is OFDM. Partial transmit sequence (PTS) combining can improve the PAR statistics of an OFDM signal. For PTS, the search complexity increases exponentially with the num-ber of subblocks. Here, we present a new algorithm for computing the phase factors that achieves better performance than the exhaustive bi-nary search approach. We also investigate the effects of non-linear am-plifiers on the performance of the new algorithm, including the power spectral density and in-band distortion. In this paper with the help of new algorithm the PAPR reduction with the PTS technique is about 1. 78 dB for 0. 01 % of input symbols. This reduction in PAPR with PTS can be increased by increasing the number of phase sequences and the size of input data block. The simulation results show that PAPR is reduced to 2. 69 dB for 0. 01 % of input symbols for increasing the number of phase sequences from 16 to 36.
