PAPR Reduction Based on Weighted OFDM with Product Block Codes for Wireless Communication

A. Seddiki, M. Djebbouri and A. Taleb-Ahmed    

Abstract: In this study, we investigate the potential of some of the well know linear block codes in reducing the peak-to-average power ratio (PAPR). The influence of combined weighting and product block coding on the PAPR is investigated. A class of constructed product block codes based on BCH block codes capable of both error correction and PAPR reduction together with several weighting functions is considered. We investigate the interplay of various weighting functions with product codes in order to minimize PAPR. Proposed scheme reduce PAPR significantly as is evident from the simulation results.
