A NOVEL SINGLE SIDEBAND SUBCARRIER MULTIPLEXING TECHNIQUE FOR RADIO OVER FIBER COMMUNICATION SYSTEMS

Radio over Fiber (RoF) is an amalgamation of optical communication with wireless access technology. In Radio over Fiber system the radio signal is modulated on to light and distributed over optical fiber cable to various Radio Access Units (RAU). These RAUs to convert the optical signal to an electrical signal, amplify and transmit it. The performance of RoF can be enhanced by using several systems which include Subcarrier Multiplexing System (SCM). Double sideband and Optical single sideband modulation has been done in SCM system and analyzed. A full duplex SCM system using Fiber Bragg Grating (FBG) is proposed. The number of users for this full duplex SCM system is further enhanced by using optical comb techniques. The modulator performance in various configurations is analyzed in this paper.
