摘要
A full-duplex radio-over-fiber system using frequency-twelvefold optical millimeter-wave based on external modulation via a Mach-Zehnder modulator is proposed and analyzed theoretically. The simulation results show that the power penalties for both the downstream and upstream signals are less than 0.5 dB. In this scheme, the configuration of a base station is simplified without laser, while the frequency of local oscillator signal is largely reduced due to the frequency-twelvefold millimeter-wave technique. The cost of the new system is largely reduced.
