Optimal Multiple Source Location via the EM (Estimate-Maximize) Algorithm

Abstract

A computationally efficient scheme for multiple-source location estimation, based on the Estimate-Maximize (EM) algorithm (1), is presented. The proposed scheme is optimal in the sense that it converges iteratively to the exact Maximum Likelihood estimate of all source location parameters simultaneously. Version of the algorithm that incorporate the estimation of the unknown amplitude attenuations and the estimation of the unknown signal waveforms are also presented. Keywords: Array processing; Multiple source. (JHD)
