Abstract

In this paper we propose the Peak to Average Power ratio reduction (PAPR) in OFDM using adapting coding technique with pre-distortion method to decrease the nonlinear distortion and to improve the power efficiency of the non-linear high power amplifier (HPA). In the proposed method adaptive coding is used for error correction as well as PAPR reduction. The pre-distorter improves the bit error rate performance of the system.
