Performance Improvement through Diversity Reception for Bluetooth in the Presence of Interference

Abstract

In this work, we propose an analytical framework to derive the performance of Bluetooth (BT) in the presence of an IEEE802.11g interferer. In particular, aiming at improving the performance of BT in the presence of interference still maintaining low the complexity, we propose a selection diversity scheme at the receiver side of the BT system and we exploit the spatial diversity to improve the coexistence between different systems sharing resources. We firstly analytically derive the BT performance in terms of mean block error probability and mean packet error probability averaged over Rayleigh fading, then we extend the analysis to the evaluation of the packet error outage, an important figure of merit when real time scenarios are considered. We show that a not negligible improvement for the coexistence issue of the involved systems can be achieved.
