摘要: 采用稀疏分量分析方法,研究了基于稀疏表示的欠定混叠盲信号分离的可恢复性,给出了在l2范数下,源信号可恢复的充分必要条件,并进一步讨论了l2范数解对噪声的鲁棒性.

关键词: 欠定混叠; 盲信号分离; 稀疏表示; l2范数解;

Abstract: By adopting the method of sparse component analysis,it discusses the recoverability of underdetermined blind source separation based on sparse representation.It establishes the sufficient and necessary conditions of source’s recoverability under l2-norm.And it further discusses the robustness of the l2-norm solution to additive noise.

Key words: underdetermined mixing; blind source separation; sparse representation; l-norm solution;
