摘要： Disclosed is a method for detecting and correcting amplitude and phase imbalances between in-phase (I) and quadrature-phase (Q) components in a high-speed wireless communication quadrature demodulator, which comprises: a) comparing an input signal with a signal determined by a quadrant to which the input signal belongs, and detecting imbalances between I and Q components with respect to the input signal; and b) using the imbalances detected in a) to correct the input signal. The present invention prevents distorting of the demodulator's performance caused by the imbalances to between I and Q components and increases application to high-speed wireless communication.
