Abstract :
Three algorithms for use with the adaptive delay filter structure are presented and compared. The three algorithms are: the maximum deviation from repression line algorithm, the delay selection from variance threshold algorithm, and the delay selection from cross-covariance algorithm. The performance of these algorithms in system modeling of a multipath echo cancellation environment is compared under various assumptions
