Abstract
In this paper, the channel characteristics of OFDM mobile communications is analyzed. Base on it the channel estimation method of transform domain processing is introduced and analyzed with comb-type pilot sub-carrier arrangement. The comparison between it and the method of linear interpolation channel estimation with different SNR and pilot intervals shows that the purpose method has the best performance. It will be useful in channel estimation on the direction of frequency for its real-time and precision in channel estimation.
