中文说明：
在信噪比从0到30dB的范围内产生8PSK，bpsk，qpsk，16qam，64qam信号，通过AWGN信道，并计算信号的高阶累积量和二阶矩，可以用于盲检测。
English Description：
8PSK, BPSK, QPSK, 16QAM and 64QAM signals are generated in the range of signal-to-noise ratio from 0 to 30dB. They pass through AWGN channel and calculate the high-order cumulant and second-order moment of the signal, which can be used for blind detection
