Abstract:
The use of Impulse Radio-Ultra Wide Band (IR-UWB) introduced a low data rate and low power consumption systems, which are suitable for sensor networks. Due to strict regulations of the power transmission and frequency use, the range and usage of IR-UWB remained very limited. To enlarge the range of UWB, this paper presents a system design on how to replace the radio part of the physical layer (PHY) of UWB by free space optics, without changing the major parts of the standard, including frame structure and coding. The performance of such a system on optical links is analyzed in Monte-Carlo simulation. The utilization of optical links will offer new configurations for uplink and downlink. This system will deal with optical noise and optical multipath channel and shows the performances of the new system in presence of Line of Sight (LOS) and diffuse links.
