Novel UWB Multi-Piconet System Interference Modeling and Performance Evaluation

UWB system that utilizes the unlicensed 3.1 – 10.6 GHz UWB band, as regulated in the United States by the Federal Communications Commission (FCC) Regulations. It is a trend that UWB and Bluetooth Technology will be combined together for developing a next-generation low-power, low-cost ad hoc networking solution that will expand Bluetooth technology’s current success. In this paper, we propose a novel piconet system model in which Bluetooth topology and MB-OFDM UWB technology are combined together to form a new ad hoc piconet system. For our proposed system, firstly, we used Bluetooth piconet’s topology as reference to construct our proposed system’s topology, considering both the path-loss effect and the using of TFC code to model our proposed scheme’s Inter-piconet Interference. Secondly, we use the PER graph to evaluate our proposed system’s performance taking account of the Inter-piconet Interference influence. Definitely, our model can be considered to provide a solid foundation for future interference aware UWB-Bluetooth protocols.
