The high peak-to-average-power-ratio (PAPR) of OFDM systems introduces inevitable non-linear distortion in the transmitter and reduces the performance dramatically. This paper proposes a novel scheme to reduce the PAPR with an adaptive dynamic range companding (ADRC) technique. Based on the examination of the distribution of OFDM signal amplitude, reduction of the PAPR is achieved by using a companding transformation and changing the distribution of the amplitude.
