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