A Practical Approach to the Estimation of Amplitude and Time Delay Parameters of a Composite Signal

Abstract

A method for estimating the amplitude and time delay parameters for signals which can be represented as a sum of a number of scaled and delayed replicas of a known signal in the presence of non-white Gaussian noise is presented. The method is based upon the principles of maximum likelihood estimation but at certain key points simplifying assumptions are made that result in a computationally practical estimation scheme. The results are compared with other related results in the literature.
