M&M载波恢复算法的MATLAB实现

principal component analysis(PCA)主成分分析，Matlab实例代码(principal component analysis(PCA))

再matlab上实现基于扩频的数字水印。图像处理(This is a simple spread-spectrum based informed watermarking implementation in MATLAB. )

应用数字信号处理matlab工具箱（数字信号处理）(Application of Matlab toolbox for digital signal processing (digital signal processing).)

说明：  利用平面波展开发计算二维光子晶体的能带结构(Show the development of the use of plane-wave calculation of two-dimensional photonic crystal band structure)

continuous time analog filters group delay

LMD实验程序，效果不太理想，与大家讨论共享。只能分享出PF1.不能实现PF2,PF3的分离(LMD experimental procedure, the effect is not ideal, discuss and share. Only share the PF1. Separation can not be achieved PF2, PF3 the)

信道主要模拟信号的多径传输，在这个信道中一共有三个用户的数据进行传输，用户一经过了2径衰落，用户二经过了3径衰落，用户三经过了4径衰落。(The main channel simulation of multipath signal transmission, in this channel has a total of three users of the data transmission, the user after 2 path fading, the user of two after 3 path fading, the user of three after 4 path fading. )

互质doa算法，研究在互质阵列下的doa估计问题，有效估计目标角度(Co DOA algorithm, the estimation problem in the DOA array of Coprime, efficient estimation of the target angle)

运用hough变换进行圆检测，能够检测圆形物体。 (Hough circle detection for use)

说明：  RD算法作为SAR处理中最重要的处理算法，在远场近似的条件下，可将二维处理分离为两个一维处理，降低了运算量，成像效果良好。(RD算法作为SAR处理中最重要的处理算法，在远场近似的条件下，可将二维处理分离为两个一维处理，降低了运算量，成像效果良好。 RD algorithm is the most important processing algorithm in processing SAR, in the far field approximation, the two-dimensional separation into two one-dimensional processing, reduces the amount of computation, good imaging effect. )
