Patent ID: 7912151

Claim:
A receiver for receiving a signal having embedded therein symbols, the receiver comprising: an input amplifier configured to receive an input signal, wherein the input amplifier is configured to generate an amplified output and a signal strength indicator, wherein the signal strength indicator comprises an indication of a gain nonlinearity of the input amplifier; and a filter operatively coupled to the input amplifier to receive the amplified output and to receive the signal strength indicator, wherein the filter is configured to vary filtering depending on a state of the signal strength indicator, and wherein the filter is configured to determine symbols embedded in the signal, wherein the filter comprises a decision feedback equalizer, wherein the decision feedback equalizer further comprises: a first feedback path with at least a first coefficient cH; a second feedback path with at least a second coefficient cL; and a multiplexer coupled to the signal strength indicator for control and to the first feedback path or the second feedback path for inputs, the multiplexer selecting the first feedback path or the second feedback path depending on the state of the signal strength indicator.
