Abstract In this paper a new method of OFDM channel estimation with noise reduction, based on wavelet transform, is given. The channel estimation algorithm is divided into least-squares estimation and noise reduction. The method does not need any statistical characteristic of channel and has good performance, compared with least-squares estimation. The conclusion is proved by computer simulation .
