来自maxim公司的噪声系数测试方法，包括详细的图表信息。(Noise from the maxim' s testing methods, including a detailed chart information.)

David G.Lowe的SIFT算子在Matlab环境下的实现，尺度不变的特征提取，并对两幅图片的特征点进行匹配，运行前要把siftWin32文件放在Matlab的win目录下，具体请参照README。默认为输入为灰度图像，要处理彩色图片请先转灰度rgb2gray() (The realization of SIFT operator David G.Lowe in the Matlab environment, the scale invariant feature extraction, matching and pictures of the two feature points, the siftWin32 file in the Matlab win directory to run before, please refer to the specific README. The default is the input for the gray image to color image processing, please turn gray by rgb2gray ())

很完善的一个OFDM仿真程序,它以FUNCTION的形式,再现了OFDM映射,IDFTDFT,同步(时间频率同步)和信道估计,以及频率偏移的估计等一系列代码.(very sound one OFDM simulation program, which is in the form FUNCTION, Reproduction of OFDM mapping, IDFTDFT, synchronous (time-frequency synchronous) and channel estimation, and the estimated frequency offset a series of code.)

本例很好的解释了FFT变换的功能，例程简单易懂，能够很好的用于理解FFT，观察信号频谱。(In this case a good explanation of the function of FFT transform routines easy to understand, can be very good for understanding the FFT, observe the signal spectrum.)

说明：  用GA算法优化极限学习机的参数，从而实现预测(GA algorithm is used to optimize the parameters of the extreme learning machine to realize the prediction)

这是一个用matlab实现的人脸识别的pca方法，正确识别率不错。(err)

music算法的变种，基于变化信噪比，用于DOA估计。(music algorithm variants, based on the change in signal to noise ratio for the DOA estimates.)

说明：  BPSK 在瑞利衰落信道中的信噪比的MATLAB仿真。。(BPSK in Rayleigh fading channel signal to noise ratio of the MATLAB simulation. .)

该程序主要用于matlab对图像进行区域检测分割 其原理是区域生长法 需要自己设定阈值 选取生长点(The program is mainly used matlab image area detection principle is divided region growing needs its own set threshold growing point)
