Abstract :
In this correspondence, a new adaptive delay estimator using only two LMS filters is presented. Compared with other algorithms, a significant reduction in computational complexity is obtained because only time domain processing is required. In addition, a new frequency-domain adaptive delay estimator has been introduced, and the link between both methods is clarified. Comparison with algorithms described in literature turns out favorably
