Abstract
A receiver circuit of a transceiver is disclosed including: a calibration circuit arranged to operably perform an I/Q mismatch calibration operation according to an in-phase detection signal and a quadrature detection signal to generate one or more compensation parameters; a parameter storage circuit; an interference detection circuit arranged to operably generate an estimated signal-to-interference ratio according to the in-phase detection signal and the quadrature detection signal; a receiver control circuit arranged to operably determine whether to discard the one or more compensation parameters, wherein the receiver control circuit stores the one or more compensation parameters into the parameter storage circuit only if the estimated signal-to-interference ratio exceeds a predetermined threshold.
