Comparison of two adaptive methods for time delay estimation
Abstract
Two adaptive algorithms for estimating the time delay between two-sensor outputs are compared. These methods are similar in that they employ the least mean square (LMS) gradient approach to estimate the time difference of arrival to two sensors. However, they involve the LMS gradient method in different ways, and thus have different properties. Some theoretical aspects are addressed. Also, they are compared via computer simulations for a variety of cases, including time-varying delay functions corresponding to moving source or receivers.
