New perspectives for maximum-likelihood parameter and time delay estimation using two channels
J.A. Stuller, Nancy Hubing · 2002
This paper introduces a new realization for maximum likelihood parameter and time-delay estimation using two channels. We obtain the result by using coupled Karhunen-Loeve expansions to derive the likelihood function. The new realization illuminates the analytical relationship between maximum likelihood time-delay estimation and other methods. Experimental results that support the theoretical findings are included.
