MAP-Based Underdetermined Blind Source Separation of Convolutive Mixtures by Hierarchical Clustering and <inline-formula><graphic file="1687-6180-2007-024717-i1.gif"/></inline-formula>-Norm Minimization
<p/> <p>We address the problem of underdetermined BSS. While most previous approaches are designed for instantaneous mixtures, we propose a time-frequency-domain algorithm for convolutive mixtures. We adopt a two-step method based on a general maximum a posteriori (MAP) approach. In the...
