中文说明： 连续相位调制信号(CPM)产生，课程设计时编写的matlab程序代码，包含特征值与特征向量的提取、训练样本以及最后的识别，实现了对10个数字音的识别，利用最小二乘算法实现对三维平面的拟合，粒子图像分割及匹配均为自行编制的子例程。
English Description：
Continuous phase modulation (CPM) were generated and curriculum design prepared by the matlab code, contain feature value and feature vector extraction, training samples and the final recognition, the identification of 10 digital audio, using least squares algorithm to achieve the 3D plane fitting, particle image segmentation and matching are compiled by the subroutine.
