The main drawback of the OFDM is its high peak to average power ratio(PAPR).There are several PAPR reduction techniques. Among the various PAPR reduction techniques, companding transform is attractive for its simplicity and effectiveness. This paper proposes a new companding algorithm. The proposed algorithm offers an improved bit error rate and minimized out-of-band interference while reducing PAPR effectively, compared with the others. Theoretical analysis and numerical simulation are presented.
