Abstract
This paper investigates hybrid fiber-radio networks for in-building
distribution of ultrawideband (UWB) signals, in order to extend UWB radio
coverage area. An original multipoint to multipoint UWB-over-fiber system,
proposed in the frame of BILBAO project, is presented and discussed. System
link gain and noise figure are evaluated through theoretical analysis. A
simulation model is used to study the impact of E/O transceivers
nonlinearity on UWB signals. Experimental results show good agreement with
simulation results. A high data rate file transfer, with UWB radio
propagation and transmission over 100 m of multimode fiber, has been also
successfully demonstrated.
