摘要：
Provided are an apparatus and a method for estimating I/Q unbalance parameters in an OFDM receiver. The apparatus includes an unbalance parameter estimator and an I/Q unbalance compensator. The unbalance parameter estimator estimates an amplitude difference and a phase difference depending on positions of pilot tones in a preamble of a received signal. The I/Q unbalance compensator compensates for an I/Q unbalance using the amplitude difference and the phase difference estimated by the unbalance parameter estimator.
