摘要： An apparatus and method of an OFDM system for compensating IQ imbalance. The apparatus includes a mixer module for mixing a wireless signal to generate a pair of in-phase and quadrature-phase analog signals; an in-phase and quadrature-phase imbalance parameter estimation unit coupled to the mixer module for estimating a gain compensation value and a phase compensation value; and a signal compensation module coupled to the in-phase and quadrature-phase imbalance parameter estimation unit for compensating the pair of in-phase and quadrature-phase analog signals for gain imbalance and phase imbalance, according to the gain compensation value and the phase compensation value respectively.
