Hybrid UWB Multi-Piconet Network Interference Modeling and Performance Enhancement by 6-Bands MB-OFDM

UWB (ultra-wide band) 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, and there is a trend that UWB and Bluetooth technology are 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 devices are combined together to form a new ad hoc piconet system. For our proposed system, first, 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. Second, we use the BER graph to evaluate our proposed system´s performance taking into account of the Inter-piconet Interference influence, furthermore, we propose a 6-Bands MB-OFDM model to enhance our network´s BER performance. Definitely, our model can be considered to provide a solid foundation for future interference aware UWB-Bluetooth protocols.
