Patent ID: 8924833

Claim:
A system for adjusting an analog front end, comprising: a signal equality estimator configured to: input one or more digital samples; determine a signal quality based at least in part on the digital samples; and determine if the signal quality satisfies one or more criteria; a data independent error computation block configured to generate a data independent gain gradient and a data independent offset gradient without taking into consideration an instantaneous value of an expected signal; a decision directed error computation block configured to generate a decision directed gain gradient and a decision directed offset gradient based at least in part on one or more decisions; and a multiplexer configured to: in the event it is determined that the signal quality satisfies the criteria, select the data independent gain gradient and the data independent offset gradient to adjust the analog front end; and in the event it is determined that the signal quality does not satisfy the criteria, select the decision directed gain gradient and the decision directed offset gradient to adjust the analog front end.
