A wireless receiver includes a feedback path, and a main path. The feedback path feeds back a first signal at a predetermined frequency range to remove a desired signal at the predetermined frequency range, and the feedback path to outputs an accumulated blocker error signal. The predetermined frequency range is lower than a radio frequency (RF) range. The main path subtracts the accumulated blocker error signal from a second signal including a blocker signal at the RF range to generate a third signal and down-converts the third signal to output the first signal at the predetermined frequency range.
