I/Q Linear Phase Imbalance Estimation Technique of the Wideband Zero-IF Receiver

I/Q Linear Phase Imbalance Estimation Technique of the Wideband Zero-IF Receiver

The in-phase/quadrature (I/Q) imbalance encountered in the zero-IF receiver leads to incomplete image frequency suppression, which severely deteriorates image rejection ratio (IRR) of the receiver system and must be improved using additional analog or digital signal processing. The I/Q linear phase...
