Efficient Application of Selected Mapping with Clipping for PAPR Reduction in OFDM Systems
Journal Title: Bonfring International Journal of Research in Communication Engineering - Year 2014, Vol 4, Issue 1
Abstract
Orthogonal Frequency Division Multiplexing (OFDM) is an inimitable technology in wireless communication. High peak-to-average power ratio (PAPR) is a challenging issue in OFDM system. Large PAPR results in significant distortion in OFDM signal when passed through nonlinear high power amplifier. Selected mapping (SLM) is an efficient technique to reduce PAPR. In this work we efficiently apply SLM technique with clipping to reduce PAPR. And the simulation results show that the proposed techniques have better PAPR reduction performance than conventional Selected Mapping technique and SLM with interleaving
