说明：  基于四阶统计最大化的盲源信号分离技术，可实现复数形式的盲源信号分离，观测混合信号需要大于等于源信号个数(Blind source signal separation technology based on four-order statistical maximization can realize the separation of blind source signal in plural form, and the need to observe mixed signal is greater than equal to the number of source signal.)

Discrete convolution in matlab

this is a program that is useful to represent a sinusoidal signal and add two sinus using a white noise, then the convolution and correlation in representing the gaits is applied.
