Abstract

This invention discloses a method for generating radio signals and wire baseband at the same time by a double-arm modulator and a single-wavelength light source in a radio-on-fiber(ROF) communicastion system and a system for transmitting two kinds of signals simultaneously on a same wavelength by fiber, which utilizes a dual-webbing modulation and a optical filter theory to generate dual-webbing signals and filter ROF mm waves and baseband data signals from down link to be provided to different users, and this invented system is not only used in single-channel ROF system but also used in WDM ROF system.

Description

(1) Technical field

[0001] The invention belongs to the technical field of a radio-over-fiber (Radio-over-Fiber, abbreviated as ROF) communication system, and can simultaneously provide wired services and wireless services. (2) Background technology

[0002] Wireless and broadband are hot spots in today's communication industry and even the entire information industry. In today's information society, there is an increasingly urgent need for multimedia communications including voice, data, and images. People hope that these communication services can be provided to individuals (no matter where the person is) at any time. Wireless communication enables people to communicate with anyone anytime and anywhere, and broadband communication can transmit data, Internet, voice, video and multimedia applications to business and home users. The combination of the two has undoubtedly become the development direction of communication.

[0003] However, in recent years, due to the underut...
