Abstract
This paper deals with 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. Recently, we proposed a criterion for solving the blind deconvolution problem [8], [9]. However, we have not yet shown an algorithm to implement our proposed criterion. One of our objectives in the present paper is to propose an iterative algorithm for achieving the blind deconvolution by using this criterion. To achieve this objective, we consider an approach called the non-deflation method. We propose an iterative algorithm based on the method. Moreover, we present a deflation algorithm using this criterion for the blind separation of MIMO constant channels.
