说明：  利用ICI self-cancellation method自我相消的方法使用在OFDM系統,AWGN通道看出在不同頻率偏移下ICI相消係數權重的大小
(The use of ICI self-cancellation method of self-phase elimination method used in the OFDM system, AWGN channel seen at different frequencies under the ICI offset relative to the size of the extinction coefficient of weight)
