Abstract :
This paper demonstrates that the LMS adaptive line enhancer (ALE) can be used to enhance estimation-performance in situations where source signal spectra have tonal components. Time delay estimation obtained by using ALE´s as pre-filters followed by a cross correlator (ALE-CC) achieve better performance than the smoothed coherence transform (SCOT) when tonals are present while achieving the basic cross-correlation performance in purely broadband conditions.
