A Comparison between Clipping and μ-Law Companding Schemes for the Reduction of Peak-to-Average Power Ratio of OFDM
Signal clipping and μ-law companding have been suggested as simple and effective peak-to- average power ratio (PAPR) reduction schemes for orthogonal frequency-division multiplexing (OFDM). This paper, addresses the problem of PAPR and the relation between it and the number of subcarriers, and analyzes clipped and companded M-ary phase-shift keying (M-PSK) OFDM signals. Their performance in AWGN channel with the presence of nonlinear power amplifier is evaluated and compared using computer simulation.
