Described embodiments adjust configurable parameters of at least one filter of a communication system. The method includes conditioning, by an analog front end (AFE) of a receiver in the communication system, an input signal applied to the receiver. Sampled values of the conditioned input signal are generated and digitized. An error detection module generates an error signal based on digitized values of the input signal and a target value. A decision feedback equalizer generates an adjustment signal based on the digitized values of the input signal and values of the error signal. A summer subtracts the adjustment signal from the conditioned input signal, generating an adjusted input signal. An adaptation module determines a conditional adaptation signal based on a comparison of sampled values of the adjusted input signal and values of the error signal. The adaptation module adjusts a transfer function of at least one filter based on the conditional adaptation signal.
