关于声源定位的源代码，主要是用ICA来解决多生源分离的问题(About the source code for sound localization, ICA is mainly used to solve the problem of separation of more than students)

过这个程序，可以更加深入的了解FIR滤波是如何实现的。用AVR单片机 ATMEGA16L实现32阶FIR低通滤波器设计，低通截止频率为200HZ。原始信号经过AD采集后进行FIR运算，处理好的数据通过串口输出。(About this program, a more in-depth understanding of the FIR filter is how to achieve. The 32-order FIR low-pass filter design, low-pass cut-off frequency AVR microcontroller ATMEGA16L 200HZ. The original signal after AD collection, the FIR computation, the output of the processed data through the serial port.)

基-4FFT算法，数字信号处理课程的基础算法之一(Group-4FFT algorithm, one of the basic algorithm for digital signal processing courses)

维纳噪声抑制，设计p阶的最优FIR维纳滤波器，估计平均平方误差， 试针对p=12的情况，分别取几个不同的权值(如0.1, 0.5, 1.0)，研究这时的噪声抑制性能。(Wiener noise suppression, the optimal design of p-order FIR Wiener filter, estimated mean square error, try the case for p = 12, respectively, the right to take several different values (such as 0.1, 0.5, 1.0), study time noise suppression performance.)

MATLAB 6_5 辅助优化计算与设计 1、文件命名说明 a)文件夹“第1章”中的文件对应书中第1章的例程，其他以此类推； b) 文件名exampleX1_X2.m：对应例程X1_X2 例如：example2_1表示例程2_1. 2、注意 为了方便起见，书中的每一个例程存为一个文件；而有些例程中将其调用的函数文件也放在这个例程文件中，所以读者在运行光盘中的例程文件时注意这一点，如果是这样的例程文件应该将其调用的函数文件分离出来另存为一个文件。(MATLAB 6_5 Auxiliary and Design Optimization 1, Note document naming a) folder "Chapter 1" in the document corresponding book Chapter 1 of the routines, other analogy; b) Name exampleX1_X2.m : X1_X2 corresponding routines such as : example2_1 said two compression routines. 2, the attention for the sake of convenience, Each book deposit for a routine one; Some routines will call a function of its documents on the routines document, Therefore, the reader is running the routines CD document to this point, If this is the routine document should be called to separate the function documents saved as a file.)
