BPSK平坦瑞利信道下的最大信噪比合并仿真的matlab程序，希望大家下载(BPSK Rayleigh flat channel with the greatest signal-to-noise ratio of Matlab simulation procedures in the hope that you download)

说明：  运用Crank-Nicholson差分格式，模拟不同初始风场、垂向涡动系数和风应力拖曳系数下，Ekman风海流随时间的变化情况。(The crank Nicholson difference scheme is used to simulate the change of Ekman wind current with time under different initial wind field, vertical eddy coefficient and wind stress drag coefficient.)

压缩感知技术中两篇重要的PPT文档，来自海外，有助于理解基本匹配算法及其拓展，以及近三年来CS研究进展。(Compressed sensing technology in two important PPT document, from overseas, helping to understand the basic matching algorithm and its development, as well as the past three years CS research progress.)

lms echo cancellation

this is a simulation of the problem random walk , coded in c

Watermarking, as opposed to steganography, has an additional requirement of robustness against possible attacks. An ideal steganographic system would embed a large amount of information perfectly securely, with no visible degradation to the cover object.

模式识别中的bayes判别分析算法，有PMUSIC 校正前和校正后的比较，实现了图像的加水印，去噪，加噪声等功能。( Pattern Recognition bayes discriminant analysis algorithm, A relatively before correction and after correction PMUSIC, Realize image watermarking, de-noising, plus noise and other functions.)
