Impact of Crosstalk on MB-OFDM UWB Transmission in Radio over Fiber WDM System
Fiber optics optical communications Radio frequency photonics
2011/5/22
We experimentally investigate the impact of crosstalk on the performance of MB-OFDM UWB signal transmission in RoF WDM system. It is found that OFDM signal’s orthogonalities are almost kept after 20 k...
Beyond 2.5Gb/s Photonic Generation and Wireless Transmission of Different Pulse Modulation Formats for a High Speed Impulse Radio UWB over Fiber System
Fiber optics communications Radio frequency photonics
2011/5/22
We experimentally demonstrate beyond 2.5Gbps photonic generation of different pulse modulation formats for impulse radio ultra-wideband (IR-UWB) over fiber application. IR-UWB transmission over 20km f...
Impact of RF Noise on Transmission Performance of Multiband OFDM UWB over Fiber Systems
RF Noise Multiband OFDM UWB over Fiber Systems Transmission Performance
2011/5/15
We investigate the performance of multiband OFDM ultra wideband (UWB) signal over fiber system considering the impact of RF noise. A compensation technique is proposed to reduce RF noise impact.
A UWB over Fibre Transmitter Reconfigurable for Multiple Modulation Schemes
UWB Fibre Transmitter Multiple Modulation Schemes
2009/7/17
A UWB over fiber transmitter that can be reconfigured to implement pulse-polarity modulation, pulse-shape modulation, pulse-amplitude modulation and on-off keying modulation is proposed and demonstrat...
Low Cost Transparent Radio-over-Fibre System for UWB Based Home Network
Transparent Radio-over-Fibre System UWB Based Home Network
2008/7/30
We show for the first time the feasibility of a multipoint to multipoint architecture for the distribution of ultra wide band radio signals over multimode fibre with low cost components.
