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