说明： 本程序通过高阶累量的方式实现了ofdm信号和带载波信号的调制识别。代码均已函数形式体现，可以直接调用，并且仿真了多种信道下的信号识别，包括高斯白噪声信道，多径信道和瑞利信道。
(The program through the high-level cumulant way to achieve the ofdm signal and carrier signal modulation recognition. The code is embodied in the form of a function, which can be called directly and emulates signal identification in a variety of channels, including Gaussian white noise channels, multipath channels, and Rayleigh channels.)
