Transmission Reliability of Wireless Communication System-Based on Optical Fiber Signal Processing


 With the continuous progress of society, people’s requirements for communication technology are getting higher and higher, and the traditional communication system has not been able to meet the growing data needs of society. Therefore, it is of practical significance and guiding significance to study the transmission reliability of communication system. In this study, the wireless communication system-based on optical fiber and Class-AB technology and non-linear distortion model used for improving communication quality were briefly introduced, and then simulation analysis was carried out on the traditional simulation system and communication system designed in this study using VPI TransmissionMaker software. The results demonstrated that the proposed system had better stability than the traditional system. The comparison of the electricity frequency spectrum between the two systems showed that the proposed system could effectively suppress the third-order distortion current, and 28.6  dBm distortion current was suppressed. The Spurious Free Dynamic Range (SFDR) of the proposed system was higher, and the fit line slope of the distortion current was 5, differing from that of the traditional system, 3. which further demonstrated that the distortion current was inhibited. In conclusion, the optical communication system designed in this study can effectively improve the communication quality and increase the reliability of wireless communication.
