canny双阈值边缘检测方法 可以对图像进行边缘检测(canny edge detection dual-threshold edge detection can )

matlab实现主成分分析，提取几个主成分，实现贡献计算。(matlab to achieve the principal component analysis)

多径多普勒信道模型，包括快衰落，慢衰落，频率选择性衰落，平坦衰落等(Ruili fading channel simulation, including delays, multi-path condition, the simulation can directly call functions)

说明：  一个介绍语音处理软件praat的文档，里面详细有praat各个部分的介绍(one document that introduces how to use Praat)

This is the matlab code for SVD-DCT image watermarking

这是进行小波边缘检测的程序，用matlab编程，小波比其他算子具有一定的优势。(This is the wavelet edge detection procedure, using matlab programming, wavelet than other operators have certain advantages.)

说明：  最坏情况鲁棒自适应波束形成优化。实际应用中,由于阵元位置的细微偏差、阵元之间的幅度相位响应也不可能完全相同、以及有限采样效应等因素,使得实际的方向矢量与其理想值之间存在误差,严重影响了波束的性能。针对这一问题，论文作者在最坏情况下自适应波束形成方法进行研究，并作比较。(Worst case robust adaptive beamforming optimization. In practical applications, the errors between the actual direction vector and its ideal value are caused by the slight deviation of the element position, the impossibility of identical amplitude and phase responses between the elements, and the limited sampling effect, which seriously affects the performance of the beam. In order to solve this problem, the author of this paper studies and compares the adaptive beamforming methods in the worst case.)
