ABSTRACT
In this paper, we propose a new iterative algorithm to solve the
 blind deconvolution problem of MIMO-FIR channels driven by source
 signals which are temporally second-order uncorrelated but fourth-order
 correlated and spatially second- and fourth-order uncorrelated.
In our new approach, to solve the blind deconvolution problem, we consider two
stages: First, filtered source signals are extracted from the mixtures of source signals.
Second, the source signals are recovered from the filtered source signals.
