<p>A communication system (10) includes a transmitter (12) that induces in a communication signal (16) a first component of in-phase to quadrature phase (I-Q) imbalance and a receiver (14) that adds a second component of I-Q imbalance. A digital, intermediate frequency (IF) I-Q balancer (38) compensates for the receiver-induced I-Q imbalance so that total distortion is sufficiently diminished and a data directed carrier-tracking loop (60) may then perform carrier synchronization to generate a baseband signal (70). An adaptive equalizer (64) within the carrier-tracking loop (60) may then effectively operate to compensate for additional distortions, such as the transmitter-induced I-Q imbalance.</p> |
