OFDM systems is very important when it is used in mobile communication field. Presented the performance simulation to this improved algorithm and then analyzed the simulation results. Analyzed the one-dimensional channel estimation method of cascade. An improved channel estimation method based on FFT had been adopted by windowing. And the new channel estimation method based on DCT is proposed.
