摘要
Abstract
Radio frequency(RF)tunable filtering and RF interference cancellation have always been the focus of RF interference suppression research.The combination of these two key technologies is considered to be a RF protection scheme to improve anti-known cooperative interference ability for receivers.This paper systematically sorts out the merits and drawbacks of the available RF protection circuits and summarizes the advanced technologies of RF tunable filtering and RF interference cancellation after investigation.Aiming at application requirements of anti-unknown non-cooperative interference,based on the main path of RF spectrum sensing and the auxiliary path of RF interference cancellation,the architecture of wideband adaptive RF protection(WARP)for spectrum sensing receivers is preliminarily proposed,and the difficult problems are discussed lastly.关键词
