Abstract
This paper presents a new MIMO instantaneous blind identification algorithm based on second order temporal property and Newton’s Method. Second order temporal structure is reformulated in a particular way such that each column of the unknown mixing matrix satisfies a system of nonlinear multivariate homogeneous polynomial equations. The nonlinear system is solved by Newton’s method for the equations. Our algorithm allows estimating the mixing matrix for scenarios with 4 sources and 3 sensors, etc. Simulations and comparisons show its effective with more accurate solutions than the algorithm with homotopy method.
