Patent ID: 7489725

Claim:
A receiver comprising: a feedforward filter coupled to process signals received by the receiver, the feedforward filter comprising, a plurality of feedforward filter taps for mitigating pre-cursor intersymbol interference, including a feedforward filter reference tap, and a coefficient for each feedforward filter tap, wherein the feedforward filter reference tap is located proximate a center position of the plurality of feedforward filter taps; a feedback filter coupled to receive signals representative of an output of the feedforward filter, the feedback filter having a plurality of feedback filter taps each having a coefficient, and a ramping circuit assembly comprising, an input port configured to receive at least one feedback filter tap coefficient from the feedback filter; a coefficient ramping circuit configured to provide a ramped output for at least one feedback filter tap coefficient, the ramped output being varied over time from a first value to a second value, the second value being dependent upon the at least one feedback filter tap coefficient, and an output port configured to communicate information representative of the ramped output to a precoder.
