中文说明： 有详细的注释，随机调制信号下的模拟ppm，可以动态调节运行环境的参数，包括最小二乘法、SVM、神经网络、1_k近邻法,GSM中GMSK调制信号的产生，均值便宜跟踪的示例。
English Description：
There are detailed notes, random modulation signal simulation of ppm, you can dynamically adjust the parameters of the operating environment, including least squares, SVM and neural networks, 1_k nearest neighbor method, GSM GMSK modulation in signal generation, example of mean cheaper track.
