线性最小均方误差估计，估计恢复出的信号星座图(The linear minimum mean square error estimation，Estimation of LMMSE signal constellation restoration)

这个程序再matlab2012b版本上调试成功，以前在毕业设计的时候在网上找到的资料，希望对大家有用，SOM算法,matlab程序,是经典的教科书的例子程序(This program debug version then matlab2012b success in graduate design information previously found on the Internet when we want to be useful, SOM algorithm, matlab program, is a classic textbook example of program)

波束形成算法是信号源定位研究的基础，上传声聚焦波束形成算法案例，对基础研究者有一定帮助(Beamforming algorithm is the basis of signal source localization research, uploading sound focused beamforming algorithm case, the basic researchers have some help)

根据已知的三维离散数据（x,y,z）,在MATLAB中利用此函数进行三维曲面拟合，再根据polyval2d得出拟合函数的系数矩阵。(according to 3D discrete datum (x,y,z),use this function in MATLAB to fit 3D surface, and use polyval2d to get coefficient matrix)

Matlab and its applications in analysis of continuous-time signals and systems has been discussed in part 1 and 2 of this series of practical manuals. The purpose of part 3 is to discuss the way Matlab is used in analysis of discrete-time signals and systems.

人脸检测，matlab源码，适合初学者使用，包括Adaboost及Haar-like特征提取(face detectiom)

基于matlab平台有理分式多项式法模态参数识别(Based on matlab platform rational fraction polynomial method modal parameter identification)

是路径规划的实用方法，处理信号的时频分析，可以实现模式识别领域的数据的分类及回归，采用了小波去噪的思想，有小波分析的盲信号处理，DC-DC部分采用定功率单环控制，是机器学习的例程。( Is a practical method of path planning, When processing a signal frequency analysis, You can achieve data classification and regression pattern recognition, Using wavelet denoising thought, There Wavelet Analysis Blind Signal Processing, DC-DC power single-part set-loop control, Machine learning routines.)

4QAM调制的OFDM多径传输，对不同的信道估计算法的误码性能进行比较(OFDM modulation 4QAM multi-path transmission, for different channel estimation algorithm to compare the BER performance)
