使用高阶累积量完成单载波和OFDM信号的的识别，对不同信噪比情况下进行了仿真，有不错的效果-Using higher order cumulants to complete the identification of single carrier signal and OFDM signal, the simulation of different signal-to-noise ratio, has a good effect

实现高阶累积量算法，并通过该算法实现BPSK\QPSK\8PSK\16QAM四种调制模式(Four modulation modes of BPSK QPSK PSK QAM are realized by using the high order cumulant algorithm.)
