| Abstract: | Super wideband Radio over Fiber （RoF） system is an important solution for the future low-cost and high-quality super broadband wireless access network. Taking into consideration many research results, the RoF system based on optical vector modulation is designed, which can increase the frequency efficiency of signals. Full-duplex RoF system based on millimeter wave phase shift keying modulation is able to simplify the structure of the base-stations and the installment of optical fiber. The multi-services hybrid optical-wireless RoF system has the capability of carrying wired and several wireless signals. The RoF-based High Definition Television （HDTV） transmission test bed is also introduced. |
