Abstract

In this paper, we propose efficient solution of an under-determined matrix equation. The matrix equations studied here appear in the study of subspace based high resolution multiparameter direction of arrival estimation. The proposed gradient based technique has at least an order of magnitude computational improvement over the existing approaches. Simulation results are provided to illustrate the proposed technique
