Abstract:
1. An apparatus, comprising: a plurality of delay elements connected in series, each delay element of the plurality of delay elements being configured to delay a respective input signal and to output a respective delayed signal; a weight generator coupled with the delay elements of the plurality of delay elements, the weight generator being configured to generate a plurality of tap weights based on the delayed signals output by the delay elements of the plurality of delay elements; a tap controller coupled with the weight generator, the tap controller being 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, each of the bias factors of the set of bias factors being based on a corresponding tap weight of the plurality of tap weights; and a summer coupled with the delay elements of the plurality of delay elements and the tap controller, the summer being configured to output a weighted signal based on the delayed signals output by the delay elements of the plurality of delay elements, the tap weight enabling signals, the tap weights of the plurality of tap weights that correspond to the tap weight enabling signals, and the bias factors of the plurality of bias factors.
