System level simulation modeling of Bluetooth voice and its interference

Wireless communications are rapidly developed and employed worldwide. Bluetooth, a burgeoning wireless local area networks (WLAN) technology, can transmit not only data but also voice signals between the wireless nodes. There are many unlicensed industrial, scientific, and medical (ISM) band radio inference source such as microwave oven, 802.11b mid Home RF devices, which would drastically influence and degrade the performance of the Bluetooth communication, especially voice communication. The effect of interference is critical while a lot of Bluetooth networks coexist. This paper addresses the performances of Bluetooth voice communication system under interference and simulates Bluetooth voice communication system using Matlab Simulink toolbox.
