Patent ID: 8428203

Claim:
An apparatus comprising: a low noise amplifier (LNA) configured to receive a radio frequency input signal, wherein the LNA is configured to generate an amplified RF signal; a downconverter operatively coupled to the LNA to receive the amplified RF signal, wherein the downconverter is configured to generate a baseband signal as an output; a slicer operatively coupled to an output of the downconverter, wherein the slicer is configured to generate hard-decision samples of ones and zeroes as an output; a processor operatively coupled to the slicer, wherein the processor is configured to analyze the hard-decision samples to generate a control signal for control of filtering of at least one frequency range of the amplified RF signal; and a controllable notch filter operatively coupled to an output of the processor and to an output of the LNA, wherein the controllable notch filter is configured to receive the control signal and to filter out the at least one frequency range from the amplified RF signal.
