pham的频域盲分离算法，可供参考，具有较好的适应性。(pham frequency domain blind separation algorithm available, has a better adaptability.)

Curvelet变换是最近图像处理较新的一种多尺度几何变换算法，有详细的快速变换fdct_wrapping的matlab代码(Curvelet transform is the latest image processing a multiscale geometric transform algorithm is relatively new, there is a rapid transformation of fdct_wrapping with the matlab code)

无功补偿SVG祝电路仿真图。运行效果良好，还需完善(SVG wish reactive power compensation circuit simulation diagram. Running well, the need to improve)

说明：  主要用于基于TDOA测距定位的卡尔曼滤波，(TDOA ranging mainly used for location-based Kalman filter,)

买原创力YCL2812开发板时，赠送的源程序，适合做数字信号处理的朋友参考，谢谢！ (Buy originality YCL2812 development board, the gift of the source, suitable for digital signal processing reference to a friend, thank you!)

关于matlab解决聚类问题的相关程序，包含蚁群算法和K均值算法，可以一看，部分附带程序，非本人原创。(About matlab to solve clustering problem related procedures, including the ant colony algorithm and K-means algorithm, one can see, some incidental proceedings, not my original.)

利用最小二乘解法进行离散数值拟合，得到逼近曲线(Discrete least-squares method for the use of numerical simulation, the approximation curve)

假定半波长间隔均匀分布线列布阵的阵元数N=16，若入射平面波为f=62.5Hz的正弦信号，信号持续时间为0.4s， 系统采样频率 =1 KHz,阵列加权为均匀加权，分别给出 a)当平面波信号分别从 0,10,20,30,40,50,60,70,80,90,100度方向入射时，指向90度的波束形成器的输出序列； b)当平面波信号分别从0:1:180度方向入射时，指向90度的波束形成器的输出序列经过平方求和后的分贝数输出（把所有181个输出绘制在同一幅图中)(Assuming N=16, f=62.5, fs=1KHz, uniform weight, and the code gives: a) 90 degree response when incidence angles are: 0: 10: 100 degrees b) 90 degree spectral response when incidence angles are: 0:1:180 degrees )

读取并存储nc文件，不同的文件里的参数可能不一样，按格式修改即可。(Read and store NC files, the parameters in different files may be different, and can be modified according to format.)
