Comparative study of five LMS-based adaptive time delay estimators

摘要

A number of adaptive algorithms have been proposed to model the delay between signals received at two spatially separated sensors using an FIR filter. Among them, there are the LMSTDE, CTDE, ETDE, SETED and ETDGE, which are computationally efficient because of The LMS implementation. These five methods are compared in terms of estimation accuracy and Computational complexity.
