Executive Summary

This paper is focused in the domain of PAPR reduction of OFDM signals. The main idea is to use a combination of data interleaving with clipping and filtering and use of optimum clipping Ratio (g) in order to increase the overall performance of the system and the PAPR, BER is evaluated in AWGN channel. The main advantage of the proposed combination lies in reducing PAPR and significantly reduction in BER in the presence of AWGN channel. Moreover, the Clipped OFDM symbols obtained by the authors' optimized Clipping and Filtering method have less in-band signal distortion and lower out-of-band radiation than the existing method.
