ABSTRACT:
A system for, and method of, blind identification of multichannel finite impulse response filters. In one embodiment, the system includes: (1) a decomposition generator configured to construct, from noisy symbols containing data, a block-Hankel structured matrix and a decomposition thereof, (2) an iterative matrix re-estimator coupled to the decomposition generator and configured iteratively to re-estimate singular vectors corresponding to a scalar that satisfies the block-Hankel matrix until a sufficient convergence occurs, (3) a structured low-rank estimate matrix generator coupled to the iterative matrix re-estimator and configured to generate a block-Hankel structured low-rank estimate matrix related to the block-Hankel structured matrix and (4) an STLS channel estimator coupled to the structured low-rank estimate matrix generator and configured to obtain STLS channel estimates from the block-Hankel structured low-rank estimate matrix.
