Subspace methods for blind identification of multichannel FIRfilters using space-time contraction of cumulants

摘要

We show that the popular subspace method for identification ofnmultichannel systems can be implemented using particular contractions ofnhigher-order cumulants, in the case of independent, identicallyndistributed (i.i.d.) inputs. The algorithm appears to outperform thentraditional correlation-based subspace algorithm in lownsignal-to-noise-ratio (SNR) and/or correlated noise
