The blind separation algorithm is widely used in the field of speech signal processing. In this paper, an improved high-order cumulant-based blind signal separation algorithm is proposed and used for two-way speech enhancement. In this paper, the steepest descent filter Tap coefficient update algorithm.The simulation and actual recording experiments show the effectiveness of the proposed method.
