Abstract :
To solve the carrier offset and the inherent IQ imbalance problem of the popular radio receiver architecture receiver named direct-conversion receiver, a joint calibration method with blind source separation based on whitening and non-linear decorrelation theory is proposed. Simulation results verified the feasibility and validity of the algorithm mentioned above upon dealing with the joint calibration problem of the IQ imbalance and carrier offset.
