  • Method and system for detecting and correcting in-phase/quadrature imbalance in digital communication receivers
    Patent number: 6122325
    Abstract: The invention provides a method and system for correcting imbalance in in-phase and quadrature components of a modulated received signal. The method includes assuming a signal imbalance to exist in the received signal, the signal imbalance having an amplitude imbalance and a phase imbalance, generating an amplitude imbalance correction factor and a phase imbalance correction factor to lessen the signal imbalance, and re-evaluating the amplitude and phase imbalance correction factors over a set of readings of the in-phase and quadrature components until the signal imbalance is minimized.
