说明：  实现基本的pso算法（粒子群算法）和几篇文献资料(Pso realize the basic algorithm (PSO) and several literature)

dct变换离散余弦变换（Discrete Cosine Transform，简称DCT变换）是一种与傅立叶变换紧密相关的数学运算。在傅立叶级数展开式中，如果被展开的函数是实偶函数，那么其傅立叶级数中只包含余弦项，再将其离散化可导出余弦变换(Discrete Cosine Transform)

说明：  matlab程序例子在教学中的应用非常有用而且我很喜欢(matlab program examples in teaching that is useful very much so that I like it so much )

matlab经典教材，从入门到精通，值得一看。。(matlab classic textbook, from entry to the master, and worth a visit. .)

比较四分量信号的不同时频分布结果,小波分析。(Compare the results of time-frequency distribution of the four components of the signal)

关于端点检测的几种方法，语音样本是自己录制的，对传统算法做了一些改进，加入了去噪，去噪之后再进行端点检测，均调通 vad0303：自己设置调整门限为一定值 vad0310：根据能量值和过零率设置门限，自适应门限值 vad0310_2：基于比例因子的门限自调整 vad0310.m加入了噪声，端点检测前都噪声进行了处理 entropy.m：基于自适应子带频谱熵的稳健性语音端点检测 可用于语音增强及端点检测 dbdoor.m：双门限算法，用于语音端点检测。可以通过调整门限值，并加入门限自适应算法，实现语音端点检测(Several methods on endpoint detection, recording their own voice samples, the traditional algorithm has made some improvements, adding a de-noising, and then after de-noising endpoint detection are transferred through)

1/2咬尾卷积码，按照GMR1标准编写TCH3信道的FEC码(1/2convolutionl codes,according to the ETSI release 1 FEC codes for TCH3)

基于lms算法的X-LMS算法，比较适合实际模型(LMS algorithm based on X-LMS algorithm, more suitable for the actual model)
