关于bp算法来逼近一个函数，还有一些关于一些简单的matlab实验程序，包括切比雪的滤波-On the bp algorithm to approximate a function, there are some simple matlab on experimental procedures, including snow Chebyshev filter

这个是 系统辨识与自适应控制MATLAB仿真一书中的 源程序，现在免费给大家分享了！有需要的朋友抓紧了！-This is the system identification and adaptive control of MATLAB simulation of a source book, now free for everyone to share! The need to pay close attention to a friend!

一个基于DTW的的孤立词的语音识别系统，采用率为800，可以识别六个字左右的短语，是特定人的识别系统。运行时请更改工作目录：工程->设置->调试->更改工作目录即可-The DTW-based isolated word speech recognition system, using rate of 800, can identify words around the phrase, a specific person

It is a measuring hearing sensitivity in a GUI file of Matlab, this permit save 5 seconds of sound and get the modulate signal and spectrum, also have a graphic interface with Simulink...

TI G.729A编码器和解码器的代码具有良好的实施。此代码在DSP套件和定义sotware无线电测试了很多次。g.729a TI encoder and decoder code with good implementation. This code is tested many times on DSP kit and sotware defined radios.

录音部分是参照vckbase的录音api代码,结合了一小段socket(TCP)就可以用来单方说话录音了,程序分两部分一部分是(录音机+网络发送代码),一部分是(接收数据+播放波形音乐代码),由于程序只是为了自己用,很多地方没有注意错误的识别,结构也比较乱,本程序当初最头疼的就是控制损耗内存,结果用了双缓存来存储波形数据来交替的存储/清除. -part of the recording light vckbase recording api code combination of a small socket (TCP) can be used for recording a unilateral words, part of the procedure is divided into two parts (recorders network code), part of the (receiving data waveform music broadcast code), as a result of procedures only for their own use. many places no attention to the wrong identification, the structure was chaotic, most of the first procedure is a headache for the control of memory loss, Results of the double-caching to store waveform data to the turn of the storage/removals.

This code is used to calculated Pitch of the input signal.
