Abstract

We propose in this paper a companding scheme for PAPR (Peak-to-Average Power Ratio) reduction in OFBM (Orthogonal Frequency Division Multiplexing) systems. By exploiting statical distribution of OFDM transmit signals, the proposed scheme effectively reduces the PAPR by compressing the peak signals, while maintaining the average power unchanged. Simulation results are provided to show good performance of the proposed scheme.
