MATLAB 是一款数据分析和处理功能都非常强大的科技应用软件，利用它可以灵活方便地分析处理音频信号。文章介绍了用 MATLAB 软件处理音频信号的基本流程，并以实例形式列出了几款技术实现程序。(MATLAB is a data analysis and processing functions are very powerful application software, which allows flexible and convenient way of processing the audio signal. This paper introduces the audio signal processing using MATLAB software, the basic process and several examples were listed in the technology program.)

这个程序主要针对信号的调制与解调进行的编程，感觉很实用。(This program targeted signal modulation and demodulation for the program, feeling very practical.)

此为模式识别中Parzen窗法估计概率密度函数。 全部程序流程如下： 1、读取FAMALE.TXT文件把身高或体重给数组，并求x1的样本数N1和窗宽、体宽； 2、读取MALE.TXT文件把身高或体重给数组，并求x2的样本数N2和窗宽、体宽； 3、读取Test2.txt文件把对应的身高或体重给数组A并求A的样本数M； 4、利用Parzen窗法估计概率密度函数判别男女性别； 5、对本判别的错误率进行统计。 (This is the pattern recognition Parzen window method to estimate the probability density function . All program flow is as follows : 1 , read FAMALE.TXT file to height or weight to the array, and find the number of samples x1 N1 and window width , body width 2 , read MALE.TXT file to height or weight to the array, and find the number of samples x2 N2 and window width , body width 3 , read Test2.txt file to the corresponding height or weight requirements for the array A and A is the number of samples M 4 , the use of Parzen window method to estimate the probability density function of gender discrimination 5 , determine the error rate of the statistics . )

In this code, the BER performance of a system which uses sparse channel estimation is compared with a system which uses LSE channel estimation. It is shown that using sparse technique improves the performance of the system
