- W574003444 abstract "Major envisioned commercial Ultra Wideband (UWB) applications are indoor, nonetheless, the suitability of UWB technology for data communication over longer ranges may also have a relevant role in the outdoor wirelesscommunications. In this thesis work we evaluate and compare the achievable range-datarate performance of a reliable UWB communication link for long ranges, considering anImpulse Radio UWB system and the use of M-ary PAM and M-ary PPM modulations. The freespace, lognormal shadowing and two-ray path loss models are considered. We incorporatethe UWB frequency dependency of two different ground reflection materials as well asdifferent electric field polarizations in the two-ray path loss model. Furthermore, the novelrange-data rate performance analysis, evaluation and results are provided for Time-HoppingUWB Multiple Access asynchronous networks. Practical application is provided for a real lifesensor network considering the studied path loss models.Figures and tables with the achievable range-data rate performance of the UWB link areprovided. Novel results of this research work indicate that, complying with the FCC emissionlimits, a reliable outdoor UWB link can be established by compromising between BER, range,and speed of transmission. Furthermore, Time-Hopping UWB can be used for the physicallayer of different outdoor multiple access sensor networks." @default.
