Image rejection in low if receiver

Hi ALL,

in a low if receiver, if complex band pass filter is already implemented in analog BB, can the IQ imbalance calibration be adopted in digital domain to reject the image interference again? in my opinion, the IQ operation in CPF correlate the IQ signal, so it seems making a obstackle for the following IQ imbalance calibration in digital domain. Am I right? This question confused me a long time, hope some guys can help me.
