计算循环平稳信号的4累积量的算法，希望对大家有所帮助-Cyclostationary signals calculated cumulant algorithm 4, and they hope to help everyone

给出接收信号眼图及系统仿真误码率，搭建OFDM通信系统的框架，使用高阶累积量对MPSK信号进行调制识别。- The received signal is given eye and BER simulation systems, Build a framework OFDM communication system, Using high-order cumulants of MPSK signal modulation recognition.

算法优化非常好，几乎没有循环，给出接收信号眼图及系统仿真误码率，使用高阶累积量对MPSK信号进行调制识别。- Algorithm optimization is very good, almost no circulation, The received signal is given eye and BER simulation systems, Using high-order cumulants of MPSK signal modulation recognition.

主要是4阶高阶累积量的门限确定，带有识别率的程序(Threshold determination of higher order cumulants with recognition rate)
