Abstract
Disclosed is a wired cooperative multiple input multiple output (CMIMO) signal transmission method based on a multimode transmission line. The method includes the following step: selecting a type of the multimode transmission line; constructing a wired CMIMO transmission system based on the multimode transmission line; performing channel measurement to obtain a transmission coefficient matrix; judging whether the transmission coefficient matrix satisfies a full rank and reversibility and has a condition number satisfying conditions; optimizing a structure of the multimode transmission line, a multiport excitation structure, and a multiport receiving structure to obtain the transmission coefficient matrix which satisfies a full rank and reversibility and has a condition number satisfying conditions; making the transmission coefficient matrix be equivalent to a channel matrix of the wired CMIMO transmission system; and completing signal excitation, transmission and reception of the wired CMIMO transmission system based on the multimode transmission line.
