Abstract
Broadband radio-over-fiber networks are raising great interest for intrabuilding
distribution and signal processing of ultrawide-band (UWB) signals. In this
paper, a unique optical system based on an external modulator biased either
in linear or nonlinear regime has been used to realize both distribution of
multiband orthogonal frequency-division multiplexing (MB-OFDM) UWB signal
and all-optical frequency upconversion of UWB-OFDM subband. The impact of
the nonlinearity of the optical link on the MB-OFDM signal is investigated
through a simulation model of the complete UWB-over-fiber system. Results
have shown enhanced performance of upconverted MB-OFDM subband compared to
direct transmission due to optical noise reduction. First experimental results
have confirmed simulation results.
