课设的自然梯度算法源程序

code of beamforming technique

经验模态法可以做信号加强、模式识别、特征提取等,本程序是经验模态的matlab实现，(the realization of emd using matlab.it canbe used in the signal denoising ,pattern recognition and feature extraction )

在小波变换域实现图像噪声抑制，使用matlab编程，包括源代码实现及文档说明(In wavelet transform domain realizes image noise suppression, use matlab programming, including the source code of the realization of document description )

power_transfo.rar,功率电子领域matlab仿真文件，已经验证过，程序运行正常(power_transfo.rar,Power electronics field matlab simulation file, has already been verified, the normal operating procedures)

智能控制课本中的一些程序，其中有一章节是自己写的(some .m about control)

把加速度信号变为速度信号和位移信号。用的是反频谱法(Acceleration signal into a displacement signal)

符号错误率 （SER） 性能的M 进制相移键控法 (M = 4、 8、 16 和 32...)

自适应抵消与谱相减结合的单通道语音消噪算法的研究，对这方面的研究比较详细(Adaptive cancellation and spectral subtraction with the single-channel speech denoising algorithm, more detailed research in this area)

说明：  ORL人脸图像库，共40人，每人10幅图像，其中每人的前5幅作为训练样本，后5幅作为测试分类样本，统计正确分类率。分类准则为最近邻规则。 真实的图像尺寸为112x92，列向量堆积对应人脸库矩阵的每一列。 (ORL face image database, a total of 40 per 10 images, each of which the first five as training samples, after the 5 categories as a test sample, correct classification rate statistics. Classification criteria for the nearest neighbor rule. The real image size is 112x92, the corresponding column vector face database matrix accumulation of each column.)

说明：  比较全的MATLAB常用指令表与MATLAB软件符号语言工具箱，方便大家使用。(Comparison of all the MATLAB command table used sign language with the MATLAB software toolbox, facilitate the use.)
