Research and Simulation of Linear Instantaneous Blind Signal Separation Algorithm

The process of separating initial source information from mixing signal is called blind signal separation (BSS). This paper mainly introduces the original, development, and style, etc of BSS, as well as analyzes model types of BSS algorithm. We simulate two signal of a sine and a triangle wave, then mixing them by non-linear matrix. Through simulation, based on BSS technology of typical Fast ICA or JADE algorithm, we concluded that the BSS algorithm can get the accuracy separation effect. However, because the observed signals in actual project may be non-linear mixing signal, and hard to determine, BSS algorithm of further research is very significant.
