Abstract:
A system includes a first filter generating a first output signal based on an input signal. The first filter includes N tap weight coefficients, where N is an integer greater than 1. A first device updates the N tap weight coefficients of the first filter. A second filter generates a second output signal in response to the first output signal. The second filter includes M tap weight coefficients, where M is an integer greater than 1 and less than N. A second device determines a value of a first one of the M tap weight coefficients for each of multiple sampling times of the input signal. The second device updates the first one of the M tap weight coefficients based on the values of the first one of the M tap weight coefficients, a first gain constant, and a change in timing phase error of the first filter.
