<p>In one embodiment of the present invention, a method for adjusting a signal includes applying at least one of a loss compensation for frequency-dependent distortion and an offset compensation for DC-offset distortion to a data signal before or after the distortion occurs to generate an output signal. The method also includes, using a clock signal, sampling the output signal to generate a plurality of data values and an error value, each data value comprising either a high value or a low value based on the sampling of the output signal, the error value indicating residue of the distortion based on the sampling of the output signal. The method further includes selecting one or more filter patterns from a set of a plurality of filter patterns, each filter pattern comprising a plurality of data values. The method also includes monitoring the output signal for one or more patterns of data values corresponding to the one or more selected filter patterns. The method further includes detecting a pattern of data values in the output signal corresponding to one of the one or more selected filter patterns. The method also includes adjusting the at least one of the loss compensation and the offset compensation applied to the data signal based on the error value.</p> |
