Multi-Modulus algorithms using Givens rotations for blind deconvolution of MIMO systems

Abstract

The issue of blind Multiple-Input and Multiple-Output (MIMO) deconvolution of communication system is addressed. Two new iterative Blind Source Separation (BSS) algorithms are presented based on the minimization of Multi-Modulus (MM) criterion. A pre-whitening filter is utilized to transform the problem in finding a unitary beamformer matrix. Then applying iterative Givens and Hyperbolic rotations results in Givens Multi-modulus Algorithm (G-MMA) and Hyperbolic G-MMA (HG-MMA), respectively. Proposed algorithms are compared with several BSS algorithms in terms of Signal to Interference and Noise Ratio (SINR) and Symbol Error Rate (SER) and it was shown to outperform them.
