Directivity enhancement with improved beamforming for physical layer ultra‐wideband communication by pulse shaping

Abstract

In this manuscript, a methodology of pulse shape modification is used for the directivity enhancement of ultra-wideband (UWB) beam formation, to suppress the interference due to co-existing narrowband communications with UWB signals. We propose that the modified pulse shaping produces more direct beam patterns for the tapped delay line antenna arrangements. These direct beam patterns are obtained for the smaller values of inter-element spacing. This reduction of inter-element spacing can provide more space for other development and compact the size of the any UWB antenna unit.
