摘要： The present invention provides an apparatus for compensating a phase difference of a receiver, the apparatus including: an accumulating unit for accumulating a radio frequency (RF) input signal and generating an accumulated RF signal in order to minimize an effect of a background noise of the RF input signal; a early-local oscillating unit for generating a phase-early local oscillated signal based on a local oscillated signal of the receiver; a late-local oscillating unit for generating a phase-late local oscillated signal based on a local oscillated signal of the receiver; a phase early-late compensating unit for compensating a phase early-late based on the accumulated RF input signal and the phase-early and phase-late local oscillated signals; a look-up table data mapping unit for controlling a phase of the local oscillated signal with respect to a phase difference; and a feedback transmitting unit for transmitting a phase compensating data to the local oscillator.
