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；
