说明：  Matlab实现频谱分析 其幅值和相位已经标准化(Matlab achieve its amplitude spectrum and phase analysis have been standardized)

A dynamic estimation of channel is necessary before the transmission of the signals since the wireless channel is time–varying..we use MMSE method for channel estimation. The MMSE method calculates the following, MMSE channel estimator is designed to minimize the estimation MSE. The MMSE estimate the channel responses.
