在源信号和传输信道未知情况下，只利用接收天线的观测数据抽取源信号，称为盲信号分离.盲信号分离不仅是信号处理界、而且也是神经网络界的研究热点课题，在无线数据通信、雷达、图像、语音、医学以及地震信号处理等领域都具有广阔的应用前景.采用自然梯度法和分阶段学习法。(The source signal and transmission channel is unknown circumstances, using only observational data extraction receiving antenna source signal, known as blind signal separation. Blind signal separation is not only the signal processing community, but also a neural network hot topic in research circles, in the wireless data communications , radar images, audio, medical and seismic signal processing and other fields have broad application prospects. and the phases using the natural gradient learning method.)

用于求个多个信号源波达方向的旋转不变子空间算法(rotation invariant subspace for seeking the direction of arrival of multiple sources )

这是一个LDA主题模型的matlab代码，可进行中文模糊聚类分析，内涵说明，可直接使用。(This is a topic LDA model matlab code, can be Chinese fuzzy clustering analysis, meaning that can be used directly.)

说明：  智能天线的cma算法的matlab仿真,性能相当好!(smart antenna cma Matlab simulation algorithm performance is very good!)

增加了声子晶体周期条件： if (mod(ii,19)<9) u(ii,3)=2*u(ii,2)-u(ii,1)+c*(u(ii+1,2)-2*u(ii,2)+u(ii-1,2)) else u(ii,3)=2*u(ii,2)-u(ii,1)+0.5*c*(u(ii+1,2)-2*u(ii,2)+u(ii-1,2)) end(if (mod(ii,19)<9) u(ii,3)=2*u(ii,2)-u(ii,1)+c*(u(ii+1,2)-2*u(ii,2)+u(ii-1,2)) else u(ii,3)=2*u(ii,2)-u(ii,1)+0.5*c*(u(ii+1,2)-2*u(ii,2)+u(ii-1,2)) end)

matlab数字水印 通过这个程序可以给原图象加上水印 但不可以提取！(a watermark sourcecode implemented by MATLAB. By using this program, primary image can be embedded while the watermark cannot be extracted.)

介绍了各种matlab函数种类和调用方法，可以帮助大家了解各种matlab函数(it introduces the method of calling matlab function ,and it can help you understand all kinds of matlab function )

ldpc编码，随机生成H矩阵，LLR-BP算法译码，有我详细的注解，非常详尽(ldpc coding, randomly generated H matrix, LLR-BP decoding algorithm, with my detailed notes, very detailed)

Total Variation Denoising(TV denoising (scalar fidelity term) [ROF92] Reduces the total-variation of the image. Filters out noise while preserving edges. Textures and fine-scale details are also removed. In this demo the assumption is that a white Gaussian noise is added with a-priori known (or estimated) noise power (variance). The fidelity term to the input image is calculated automatically so that the power of the noise is reduced. )

基于matlab开发软件 的选择输入类型的数值计算仿真程序 迭代方法包括 1可自启动的4阶龙格库塔法 2需要使用其他方法启动的阿达姆斯法(Matlab-based software development selective types of numerical simulation program including an iterative method can be Since the start of the four-Runge- Kutta method need to use two other methods activated ADAMS France)
