We propose and experimentally demonstrate the heterodyne mixing and polarization diversity techniques in radio over fiber (ROF) systems with the advantages of high sensitivity and dispersion endurance. The generation of 2.5 Gb/s optical DPSK and PSK signals, fiber propagation and wireless transmission over 15 GHz subcarrier are illustrated with very low sensitivity of −26 and −32 dBm, respectively...
This paper presents our recent progress on advanced radio-over-fiber (ROF) technologies for in-building optical-wireless access networks, including multi-service, full duplex and polarization diversity ROF systems design, and experimental delivery of uncompressed HDTV signals. The novel polarization diversity technique is proposed to improve receiving sensitivity and increase anti-interference capacity...
A novel scheme of 2.5 Gb/s optical PSK signals transmission and ASK wireless signals generation with 15 GHz carrier based on heterodyne detection is demonstrated, which can realize polarization diversity and provide 1.3 Gb/s HDTV applications.
