Performance of UWB telecommunication system in the presence of multiple access interference

Abstract

Ultra wideband technology (UWB) is an emerging technology that has proven to be quite suitable for short range applications. This paper is part of an ongoing research for using UWB technology for positioning and remote sensing biometric information for team-sport players on a pitch, Simulation is conducted for a number of ldquoplayersrdquo who are carrying RFIDs transmitting signals with biometric information data about each player to a number of receiving antennas positioned around the field. We investigate the effect of multiple access interference (MAI) on the performance of UWB wireless systems using a novel MISO diversity combining scheme. The main goal is to determine the number of interferers that the system can handle before producing an unacceptable quality of service (QoS). The results show that, due to UWB low power spectral density characteristics, the system can handle a relatively large number of interferers.
