초록

We propose in this paper a companding scheme or peak-to-average power ratio (PAPR) reduction in orthogonal frequency division multiplexing (OFDM) systems. By exploiting statistical 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.
