A 60 GHz Radio-over-Fiber Architecture for the Transmission of UWB-OFDM Signals

摘要

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.
