Blind signal extraction (BSE) is an efficient way to recover the source signals from the observed signals. In this paper, a new adaptive algorithm of blind signal extraction based on the skewness was introduced for the signals whose probability distribution is not symmetric. The algorithm cooperated with the deflation procedure realizes the extraction of source signals one bye one. Only third-order statistics are used in the novel algorithm, so it can reduce the computational burden effectively. Computer simulations confirm the validity and performance of the algorithm
