Abstract :
The text concisely shows an idea for use of two coupled LMS filters to estimate time delay between two detectors (microphones). In the algorithm stiff shape of the impulse response is assumed. As a result, LMS algorithm adapts time delay and gain only. Time complexity of the algorithm is the same order as time computational complexity of conventional LMS algorithm. The article is illustrated by computations on real-life data
