Abstract
An apparatus for processing a received signal includes an analog-to-digital converter (ADC) configured to produce a sampled signal from a received signal using a candidate sampling phase. An adaptive filter includes adaptive filter coefficients and is configured to receive the sampled signal and converge the filter coefficients based on the candidate sampling phase. A controller includes a module for comparing the converged filter coefficients to filter coefficient thresholds, and a module for determining a largest filter coefficient among one or more excessive filter coefficients that exceed one or more corresponding filter coefficient thresholds. The apparatus is stepped through multiple candidate sampling phases. A best sampling phase is selected based on the largest filter coefficients associated with the candidate sampling phases.
