Bluetooth adaptive techniques to mitigate interference
Nada Golmie, O. Rébala · 2004
In this paper, we investigate the use of adaptive techniques to mitigate interference for Bluetooth systems in the presence of WLAN direct sequence spread spectrum devices. We consider two different techniques that attempt to avoid time and frequency collisions of WLAN and Bluetooth transmissions. We conduct a comparative analysis of their performance for several dynamic scenarios where the WLAN interference varies over time due to either change in user activity or number of non-overlapping WLAN systems. We discuss the trade-offs involved in terms of delay, packet loss performance, and synchronization.
