Abstract :
A novel blind I/Q imbalance parameter estimation and compensation scheme for low-IF receivers, which was previously proposed by the authors, is analytically analyzed in this paper. As an outcome, we present an equation for calculating the expected power ratio of image and desired signal after compensation. The excellent performance of the novel compensation scheme, which was so far justified by simulations only, is now substantiated by a solid theory.
