Abstract :
High peak to average power ratio (PAPR) is a very serious drawback in Orthogonal Frequency Division Multiplexing (OFDM). We propose the novel approach which is reduce PAPR and Computational complexity without any distortion. In these technique the phase sequence multiplication before perform IFFT operation by using PN sequence generator and second phase sequence multiplication are the invert version of PN sequence generator. After perform IFFT operation select minimum PAPR then transmitted. Which reduce the PAPR and reduce Computational complexity by using only single PN sequence generator in place of two? We show the performance of propose scheme in MATLAB environment.
