Abstract
In this paper the low-IF receiver architecture, the image interference due to the IF domain, phenomena also referred as I/Q imbalance and a complex LMS filter for image rejection are presented. A Simulink model was created to check the availability of the LMS filter, its performance measured and compared to the existing implementation. Simulation shows that the image rejection ratio is limited at 32 dB by the LMS filterpsilas learning rate.
