US Patent 11016681 Multi-threshold parameter adaptation

An apparatus may include a circuit configured to receive an input signal at an input and process the input signal using a set of channel parameters. The circuit may further determine an error metric for the processing of the input signal using the set of channel parameters, compare the error metric to a plurality of thresholds, and when the error metric matches one of the plurality of thresholds, adapt, using an adaptation algorithm, the set of channel parameters to produce an updated set of channel parameters for use by the circuit as the set of channel parameters in subsequent processing of the input signal, the adaptation of the set of channel parameters being based on a weight corresponding to the matching threshold of the plurality of thresholds.
