Abstract

In the cabin area communication scenario based on quasi-static electric field coupling, signal leakage will occur when a single channel or negative plate is grounded. This paper analyzes the cause of this problem through modeling and simulation, and proposes to use differential transmission in cabin area communication to solve the problem of signal leakage. Finally, a test prototype is made using FPGA and a test device is designed to verify the feasibility of this method.
