mi hael s.unm.edu bap s.unm.edu The blind sour e separation problem is to extra t the underlying sour e signals from a set of linear mix-tures, where the mixing matrix is unknown. We on-sider a two-stage separation pro ess. First, a pri-ori sele tion of a possibly over omplete signal di tio-nary (e.g. wavelet frame, learned di tionary, et.) in whi h the sour es are assumed to be sparsely repre-sentable. Se ond, unmixing the sour es by exploiting the their sparse representability. We onsider the gen-eral ase of more sour es than mixtures, but also de-rive a more eÆ ient algorithm in the ase of a non-over omplete di tionary and equal numbers of sour es and mixtures. Experiments with arti ial signals and with musi al sounds demonstrate ...
