Peak to Average Power Ratio Reduction in OFDM System over PAM, QAM and QPSK Modulation

Part of the Advances in Intelligent Systems and Computing book series (AISC, volume 176)

Abstract

Peak to Average Power Ratio (PAPR or PAR) is major problem of Orthogonal Frequency Division Multiplexing. The Classical Clipping method is used in this paper for reduction of PAPR using 4-PAM, 4-QAM and QPSK. Through the Analysis, it is shown that Clipping on 4-PAM is better than QPSK and 4-QAM with 64 subcarriers.
