Abstract

In this paper, focusing on the strong interference extrication and cancellation in digital and analog fields, respectively, a method of strong interference suppression in broadband satellite communication is proposed. The design approaches and implementation procedures for the extraction filter in digital field are first provided. Moreover, integrated with engineering practice, a filtering method based on mathematical morphology is presented to eliminate the effects caused by noise floor fluctuation in broadband satellite communication. Theoretical investigation and simulation results demonstrate that our proposed method can suppress the strong interference effectively.
