Abstract
A system may comprise a finite impulse response circuit configured to receive one or more samples of a first signal and generate an equalized signal based on the plurality of samples of the input signal and one or more updatable tap coefficients. The system may include an adaptation circuit configured to update the one or more updatable tap coefficients based on the plurality of samples of the input signal. The system may further comprise a recovery circuit configured to accumulate one or more retuning values based on the plurality of samples of the input signal and, in response to an error condition, generate one or more retuned tap coefficients for the finite impulse response circuit based on the one or more retuning values and replace the one or more updatable parameters with the one or more retuned parameters.
