Claim of US Patent No. 10,367,545

1. An adaptive filter using resource sharing, said adaptive filter comprising:a tapped-delay-line providing L tapped delay signals, wherein L is a filter order of the adaptive filter, wherein L is a number;
a number of computational blocks each configured for adjusting one filter coefficient, in one cycle of an iterative procedure according to an adaptive convergence algorithm, wherein the number of computational blocks is less than the filter order L;
a cluster controller configured for allocating each of the computational blocks to one of a number of w clusters, wherein w is a positive integer; and
a symbol routing logic arranged for routing a set of tapped delay signals, to each cluster,
wherein the computational blocks of each cluster are provided for adjusting the filter coefficients, associated with the set of tapped delay signals, routed to the respective one of the clusters,
wherein the computational blocks of each cluster are timely shared among the filter coefficients, of one set of tapped delay signals;
and
a routing controller provided for configuring the routing of the tapped delay signals to the respective cluster in accordance with the allocation thereof.
