ABSTRACT:
An apparatus and method for removing a jammer signal in a wireless communication receiver, in which a frequency converter down-converts a radio frequency (RF) signal including a desired and a jammer signal into a baseband signal. A first filter removes the desired signal from an output signal of the frequency converter and outputs a jammer signal as an output signal. The frequency converter up-converts the jammers signal output from the first filter. The second filter outputs the up-converted jammer signal as an output signal. The first adder receives the RF signal and the output signal of the second filter and removes the jammer signal from the RF signal using the RF signal and the output signal of the second filter. Accordingly, the frequency converter down-converts the RF signal including the attended jammer signal.
