利用MATLAB实现的两个语音的盲信号分离（BSS）~非常有用(MATLAB implementation of the two voice Blind signal separation (BSS) ~ very useful)

matlab比较比较好的代码！程序写的很详细！能够运行！(Winmax good code! Programs written in great detail! Be able to run!)

C++ 中使用matlab中的函数，一个简单的使用例子(use of Matlab function, a simple example of the use of)

VMD方法是在传统维纳滤波的基础上，提出的一种非递归自适应信号分解新方法。与EMD方法和LMD方法相比，VMD方法分解的信号，具有精度高、收敛快和鲁棒性好等特点，适用于处理滚动轴承故障信号。(The VMD method is a new non recursive adaptive signal decomposition method based on traditional Wiener filtering. Compared with the EMD method and the LMD method, the signal decomposed by the VMD method has the characteristics of high precision, fast convergence and good robustness. It is suitable for handling the fault signal of rolling bearing.)
