Selective Mapping:Implementation of PAPR Reduction Technique in OFDM on SDR Platform

Abstract

This paper presents an implementation of Selective mapping technique for Peak to Average Power Ratio (PAPR) reduction in orthogonal frequency-division multiplexing (OFDM) on Software Defined Radio (SDR) platform. OFDM is a multicarrier modulation scheme which supports high data rate transmission. High PAPR in OFDM is responsible for distortion of signal. Our interest is in implementation of PAPR reduction techniques in OFDM on SDR platform using MATLAB and XILINX. We compare the results of MATLAB and XILINX to ensure the specific reduction in PAPR on SDR platform.
