Abstract

The invention relates to full-duplex radio-over-fiber systems. A system comprises a first link and a second link. The first link is used for radio-over-fiber of a W band from a first end to a second end. The first link comprises a first transmitting device and a first receiving device. The first transmitting device sets a central wavelength of a light source, generates a W band millimeter wave through utilization of a beat frequency, modulates a first original signal to the W band millimeter wave, obtains a first modulation signal and sends the first modulation signal to the first receiving device. The first receiving device is used for receiving and demodulating the firs modulation signal, thereby obtaining the first original signal. The second link is used for the radio-over-fiber of theW band from the second end to the first end. The second link and the first link are consistent in network topology structure. According to the scheme, the W band millimeter wave is generated throughutilization of the beat frequency, network configuration operation is simple, cost is greatly reduced, and relatively high access bandwidths are realized.

Description

technical field [0001] The present invention relates to the technical field of optical fiber wireless communication, in particular to a duplex light-borne wireless communication system. Background technique [0002] Wireless and broadband are hot spots in today's communication industry and even the entire information industry. The current wireless communication system mainly uses low-frequency microwave signals with spectrum congestion, and it is difficult to break through the bottleneck of bandwidth and transmission rate. With the rapid development of broadband services, it is necessary to use wireless channels with higher operating frequencies. [0003] With the rapid development of the communications industry, 5G is getting closer and closer to formal commercialization. The existing communication network has increasing requirements on the transmission rate. This puts forward higher requirements for the development of next-generation large-capacity access technologies th...
