[IEEE 2018 International Multi-Conference on Industrial Engineering and Modern Technologies (FarEastCon) - Vladivostok (2018.10.3-2018.10.4)] 2018 International Multi-Conference on Industrial Engineering and Modern Technologies (FarEastCon) - Spectral Modulation Technique Based on Frequency-Shift Keying for High-Speed Optical Fiber-Wireless Communication System

摘要： In this paper we present novel spectral modulation technique for high-speed hybrid telecommunication systems. This technique is based on frequency-shift keying of three wideband pulses with central frequency hopping in desired sub-terahertz frequency range. Mathematical and simulation models of optimal pulses based on hyperbolic secant square function shaped to get maximum of provided power are presented. For such modulation scheme we also developed symbol coding technique that provides bit rate incensement and gains into spectral efficiency and interception security of telecommunication system. Simulation results of spectral modulated signal propagation in radio-over-fiber links are presented and discussed. Finally we introduce preliminary results for system performance with expanded number of applied pulses and advanced symbol coding technique.
