- Abstract :
Optical frequency division multiplexing (OFDM) wireless access network
using optical single-sideband modulation is proposed, which allows to
deliver different wireless signals from a central station to each base
station over an optical fiber network.
The optical single-sideband (SSB) OFDM can achieve the highest spectrum
efficiency of 0.25 b/s/Hz. A 0.25 b/s/Hz has been experimentally
verified by the error-free transport of two-channel 4.98 Gb/s BPSK
signal on 10 GHz wireless carrier with the frequency channel interval
of 20 GHz at 1550 nm over 50 km-long standard single-mode fiber link.
Furthermore, it has been also experimentally confirmed that by
introducing the polarization division multiplexing (PDM),
the ultimate spectrum efficiency of 0.5 b/s/Hz can be achieved by
the hybird OFDM/PDM.
