New perspectives for maximum likelihood time-delay estimation
J.A. Stuller, Nancy Hubing · IEEE Transactions on Signal Processing · 1997
This paper introduces a new realization for maximum likelihood time-delay estimation (TDE) that illuminates the relationships between maximum likelihood TDE and other methods. We obtain the result by deriving the likelihood function using a fundamental method that appears to be new to the field of array processing. This method is a natural complement to the generalized Karhunen-Loeve expansion.
