A 60 GHz Radio-over-Fiber architecture for the transmission of UWB-OFDM signals

This paper presents an original 60 GHz architecture for ultra-wide band (UWB) radio-over-fiber (RoF) systems to increase both the transmission distance and the high data bit rate. With a central station (CS) and a base station (BS), this architecture allows to send through an optical fiber both a subcarrier microwave signal and UWB baseband data by using a wavelength multiplexer. At the BS, the carrier frequency is photodetected, modulated by data and then up-converted to millimeter-wave band. Simulation results using VPIsystems software are reported and discussed for multi-band orthogonal frequency division multiplexing (MB-OFDM) signals.
