Wired MIMO Communication Method Based on the Multimode Transmission Line

A novel wired MIMO communication method based on the multimode transmission line is presented. Here, multiple eigenmodes supported by the multimode transmission line are used as independent paths of MIMO for capacity improvement. Different from the former wired communication using the multimode transmission line, it is not critically necessary to maintain the mode purity in excitation and transmission, and a stable channel environment is resulted for the communication accordingly using this method. For demonstration, simulations based on the dielectric-filled waveguide are carried out to investigate the operational modes and system performance. The results indicate that the proposed method is feasible, offering a solution to realize wired communication systems with high data rates and large capacities.
