Blind Mitigation of Narrowband Interference Utilizing Frequency Dependence of Array Antennas in UWB Systems
Kazutaka Kikuta, Akira Hirose (The Univ. of Tokyo) EMT2016-68
Abstract (in Japanese) (See Japanese page) 
(in English) Ultra wideband (UWB) signals require mitigation of narrowband interference (NBI) from other wireless systems. This paper proposes a novel NBI mitigation method which utilizes frequency dependence of null formation in array antennas. We use power inversion to direct nulls to narrowband large-power input, which realizes NBI-only suppression with the UWB pulse signals left almost unchanged. The proposed method is applicable to variously directional and multiple-frequency NBIs without a priori knowledge of the incident waves.
