A Novel Approach to Design a Bi-Directional Radio over Fiber SCM/ASK System for Future Generation Networks

摘要

Objective: The objective of this research paper is to design a bidirectional radio over fiber by utilizing the effect of stimulated brillouin scattering effect to provide better efficiency of the system. Methods: The core idea is to strengthen upper sideband and suppress lower sideband to realize single sideband suppressed with carrier present signal to provide capabilities for supporting radio over fiber systems. A novel frequency mover is proposed in which a dual directional sub carrier multiplexing is realized by characterizing the effect of stimulated brillouin scattering effect. The parameters are considered including the Bit Error Rate (BER) and Q-factor under acceptable range. Finding: It is found that the proposed approach describes the Sub Carrier Multiplexing (SCM) system along with the Special Broadcasting Scattering (SBS) provides better results than without considering the SBS generated signal over 10 to 40 km distance. The results for the same are compared and the applied technique is selected and the required quality for the optimal performance of the system is reported. Application/ Improvement: This approach can be applied for the future generation networks along with the use of modulated schemes like Quadrature Amplitude Modulator (QAM), Quadrature Phase Shift Keyed (QPSK) etc. Further improvements can be done by dispersion compensation in bidirectional Radio-Over-Fib (ROF).
