Abstract:

In this paper, the effect of room reflaction on blind source separation is investigated. The higher order reflection (reverberation) can be reduced in advance of blind separation by using the subspace method. On the other hand, as for the lower order reflection (early reflection), it is shown by experiments that the early reflection has little effect on the separation performance.
