Abstract

I/Q channels imbalance is one of major concerns in the design of quadrature receivers, which can influence the system performance significantly. In this paper we first analyze the effects of I/Q channels mismatches in detail, and furthermore discuss the relationship between I/Q imbalance and image signals. Then a new method for digitally measuring and correcting the imbalances is proposed based on the analytical results. In the correction process of this new method, phase errors are transferred into time errors, and later the famous Farrow structure is introduced to compensate the phase errors. Simulation results are presented to demonstrate and verify the efficacy of the proposed method.
