Full-Duplex Wireless Data Transmission Based on Cage-Coupled Structure

This paper proposes a full-duplex wireless data tr-ansmission technique for underwater autonomous vehicles based on a cage coupling structure, aiming to solve the problem of data interaction with charging stations when wireless charging is performed by existing underwater autonomous vehicles. The desig-ned cage magnetic coupling structure has good offset fault tolerance; the data transmission system realizes full-duplex communication by utilizing the double low-impedance frequency point characteristic using series-parallel resonance, which significantly improves the data transmission rate and reliability. The constructed full-duplex experimental prototype can realize the data transmission rate of 150kbps in forward direction and 250 kbps in reverse direction with low bit error rate (BER), which verifies the feasibility of this system and provides a new solution for the data interaction during wireless charging of underwater autonomous vehicles.
