| Abstract: | A new transform domain channel estimation method on orthogonal frequency division multiplexing systems was given based on discrete wavelet transform.Channel estimation signal was adapted by the discrete wavelet transform in the transform domain.Such method could better track channel change and eliminate the noise remarkably in the received pilot signal,and the precision of channel estimation had been improved. |
