Interference mitigation techniques in a high bandwidth Bluetooth access point

Abstract

Bluetooth is an emerging wireless technology over the past three years. It not only provides interconnectivity between small devices, but also makes Internet access for handheld devices possible. Due to the low data rate of Bluetooth, it is required to host multiple Bluetooth modules in a single Bluetooth access point. However, the inter-module interference would degrade the system throughput. In this paper we propose two techniques, Sequential Clock-Initialization and Address Selection, to mitigate the inter-module interference. According to the simulation results, our techniques can have performance improvements of 26% and 116% comparing to the systems without using any interference-mitigation approaches.
