Abstract :
A new adaptive line enhancer (ALE) structure, called the Feedback ALE (FALE), is presented and is shown to be a constrained W adaptive filter. Extensive simulations show that the FALE gives a higher sine-to-broadband ratio (SBR) gain and smaller sine estimation error than does an equal-order ALE; conversely, the order of the FALE can be much low er than the ALE to achieve equivalent performance
