Abstract:

The high peak-to-average (PAPR) is one of the serious problems in the application of OFDM technology. The Companding transform approach is a very attractive technique to reduce PAPR in that high bit error rate will occurred.in this paper we can combined both companding and dct(discrete cosine transforms) the proposed scheme may obtain about 1 dB PAPR reduction compared with the conventional Companding algorithm.
