Design of Long Cable Transmission System for Ocean Exploration Based on Simplified FBMC Modulation

In order to cope with the harsh and complex marine environment, this paper designs a long cable transmission system based on simplified Filter bank multicarrier (FBMC) modulation. By studying the transmission model of the long cable transmission line, a simplified FBMC modulator is designed. Finally, software simulation and hardware testing are used to verify the feasibility and stability of the long cable transmission system for data transmission in the ocean, it has reference significance for deep-sea cable transmission in ocean exploration.
