中文说明：在一个通信信号中，可能夹杂着很多干扰，其中的人为宽带数字调制类干扰更难去除，比如BPSK,QPSK干扰等。本程序对该干扰进行了盲估计，在没有干扰先验知识下，高信噪比时性能非常好。
English Description：
In a communication signal, there may be a lot of interference, among which the artificial wideband digital modulation interference is more difficult to remove, such as BPSK, QPSK interference and so on. This program has carried on the blind estimation to this interference, under no interference prior knowledge, the performance is very good when the signal-to-noise ratio is high.
