摘要： An apparatus includes a plurality of delay elements configured to delay a respective input signal and to output a respective delayed signal. The apparatus also includes a weight generator configured to generate a plurality of tap weights based on the delayed signals. The apparatus further includes a tap controller configured to generate tap weight enabling signals corresponding to one or more of the tap weights if the corresponding tap weights are greater than a predetermined threshold value. The tap controller is also configured to generate a set of bias factors based on corresponding tap weights of the plurality of tap weights.

摘要： An apparatus comprises a plurality of delay elements connected in series. Each delay element is configured to delay a respective input signal and to output a respective delayed signal. The apparatus also comprises a weight generator configured to generate a plurality of tap weights based on the delayed signals. The apparatus further comprises a tap controller configured to (1) generate tap weight enabling signals corresponding to one or more of the tap weights based on a determination that the corresponding tap weights are greater than a predetermined threshold value, and (2) generate a set of bias factors. The apparatus additionally comprises a summer configured to output a weighted signal based on the delayed signals, the tap weight enabling signals, the tap weights, and the bias factors.
