Frequency dependent mismatch correction scheme for Zero-IF receivers

Rafal Hibner, Ryszard Zielinski

Abstract


This paper shows effective method of linear distortions compensation in zero-IF receivers. With application of frequency domain processing a computation efficient method was developed that allows to correct quadrature mismatch in Zero-IF receiver along with gain and group delay independent of receiving signal type. Method was implemented and tested on hardware platform confirming its effectiveness.
