Abstract

A method and apparatus for balancing I/Q gain and I/Q phase in a signal receiver. The receiver includes an IQ coefficient calculator, an IQ balancer, and a latency time delay device. The latency time delay device delays I and Q signals by a latency time period. During the latency time the IQ coefficient calculator uses the I and Q signals during a section of the packets corresponding to the latency time period for computing correction coefficients. The IQ balancer receives the I and Q signals after the latency time period and applies the correction coefficients to the entire packet of I and Q signals.
