说明：  使用FFT变换在频域对宽带扩频信号中的正弦干扰信号进行识别和抑制，其中扩频信号由1024点的伪随机序列表示。
(In the frequency domain using the FFT transform of broadband spread-spectrum signal of sinusoidal interference signal identification and suppression, in which spread-spectrum signal is generated by pseudo-random sequence of 1024 points, said.)
