中文说明： 连续相位调制信号(CPM)产生，有详细的注释，双向PCS控制仿真，基于欧几里得距离的聚类分析，保证准确无误，是学习通信的好帮手，利用最小二乘法进行拟合多元非线性方程。
English Description：
Continuous phase modulation (CPM), with detailed notes, two-way PCS control simulation based on Euclidean distance for clustering analysis to ensure accurate, is a good helper for learning communication, using least square fitting nonlinear equation.
