Abstract
A method and apparatus for compensating I/Q imbalance in receivers is described. The method includes determining a difference between energies of two quadratures, correcting an amplitude imbalance using the difference between the energies of two quadratures, determining a cross-correlation between the two quadratures, and correcting a phase imbalance using the cross-correlation between the two quadratures.
