Blind source separation (BSS) is one active branch of stochastic signal processing. It can recover source signals from their observed mixtures without knowing the source signals and the mixing coefficients.

• 盲源分离(Blind Source Separation,BSS)是统计信号处理的一个活跃分支,它能在各源信号和传输通道参数(混合矩阵)均未知的情况下,仅仅利用源信号的多个观测(混合)信号,去恢复各源信号。
