Clustering-based Interference Suppression Algorithm for UWB Localization

Abstract

UWB (Ultra-Wideband) technology, also known as "Ultra-Wideband" or pulse radio technology, is a wireless communication system that transfers data over short distances by delivering nanosecond pulses without any carrier, with just a few tens of pW used during signal transmission. Because of its unique properties, UWB offers a wide variety of applications in diverse industries such as military and Internet of Things. The existence of multipath effects produces considerable positioning mistakes in complicated interior situations. To solve this issue, a simulated indoor environment with object occlusion and reflection is generated to recreate multipath effects. Based on this circumstance, a special strategy for suppressing multipath interference and improving localization accuracy is investigated using K-Means.
