盲信号分离应用的图像盲分离的资料，给出了事例以及部分源码(Blind Signal Separation Application Blind Image Separation of information, and gives examples of some of the FOSS)

基于 Matlab 的积分分离 PID 控制 算法及仿真 摘 要 MATLAB 是一种集数值计算、符号运算、可视化(flying car)

matlab变成实现prony算法，自动提取符合信号中分量的频率、幅值、相位、衰减系数等参数，可以实现数据拟合(matlab become realized prony algorithms automatically extract the parameters frequency, amplitude, phase, in line with the signal attenuation coefficient component, you can achieve data fitting)

用matlab进行灰色预测，先进行检验，通过后预测，然后再进行残差修正，一般一阶残差修正精度会比较好，也就够了。 有较详细的注释 %灰色预测：ForecastData=grey_forecast(A,m,translation) %灰色预测检验：[E,Q]=grey_check(A,ForecastData) %一阶残差修正Markov Chain：eMC=grey_MarkovChain(E,m) %一阶残差修正残差预测：EData=grey_forecast(abs(E),m,translation) %一阶残差修正模型最终预测：EForecast = ForecastData + eMC.*EData; %一阶残差修正模型检验：[EE,EQ]=grey_check(A,EForecast) %二阶残差修正Markov Chain：eeMC=grey_MarkovChain(EE,m) %二阶残差修正残差预测：EEData=grey_forecast(abs(EE),m,tran

The objective is to construct different line beams

说明：  这是一个相对完整的OFDM通信系统的仿真设计，包括编码，调制，IFFT， 上下变频，高斯信道建模，FFT，PAPR抑制，各种同步，解调和解码等模 块，并统括系统性能的仿真验证了系统设计的可靠性。 (This is a relatively complete simulation of OFDM communication system design, including coding, modulation, IFFT, the upper and lower frequency, Gaussian channel model, FFT, PAPR suppression, various synchronization, demodulation and decoding of modular and system performance omnibus simulation of the system reliability.)

说明：  Matlab 模拟 CDMA 直接扩频。m序列生成矩阵为p(x) = 1 + x^5 + x^7 + x^8 + x^9 + x^13 + x^15。能画出每阶段的时域、频域图。(Matlab simulation of CDMA Direct Spread Spectrum. m sequence generated matrix for p (x) = 1+ x ^ 5+ x ^ 7+ x ^ 8+ x ^ 9+ x ^ 13+ x ^ 15. To draw each stage of the time domain, frequency domain Fig.)
