In this paper, we propose a new algorithm for overdetermined blind source separation (BSS), which enables us to achieve good separation performance even for signals recorded in a reverberant environment. The proposed algorithm utilizes ex tra observations (channels) in overdetermined BSS to esti mate both direct and reverberant components of each source. This approach can relax the rank-1 spatial constraint, which corresponds to the assumption of a linear time-invariant mixing system. To… CONTINUE READING
