This paper presents an algorithm to perform source-signal estimation and separation in reverberant environment without knowing the properties of the channels. The receiver signals in our model are represented as a linear combination of filtered and delayed versions of signals of each source. The algorithm requires a reference vector to determine the channel properties. Basing on the estimated channel parameter matrices, the estimation and separation of source signals can then be achieved by a recurrence formula. Two examples are given to illustrate the validity of our algorithm.
