Wired cooperative multiple input multiple output (CMIMO) signal transmission method based on the multimode transmission line

A wired cooperative multiple input multiple output (CMIMO) signal transmission method based on a multimode transmission line, comprising following steps:

• S1:
• selecting a type of the multimode transmission line;
• S2:
• designing a structure of the multimode transmission line, a multiport excitation structure, and a multiport receiving structure based on a selected type of the multimode transmission line to construct a wired CMIMO transmission system based on the multimode transmission line;
• S3:
• performing channel measurement on an entirety formed by the multiport excitation structure, the multimode transmission line, and the multiport receiving structure to obtain a transmission coefficient matrix;
• S4:
• judging whether the transmission coefficient matrix satisfies a full rank and reversibility, and has a condition number satisfying conditions;
• if not, executing S5;
• and if yes, executing S6;
• S5:
• optimizing the structure of the multimode transmission line, the multiport excitation structure, and the multiport receiving structure to obtain the transmission coefficient matrix which satisfies the full rank and reversibility and has the condition number satisfying conditions;
• S6:
• making the transmission coefficient matrix provided by the entirety formed by the multiport excitation structure, the multimode transmission line, and the multiport receiving structure equivalent to a channel matrix of the wired CMIMO transmission system;
• and
• S7:
• completing signal excitation, transmission, and reception of the wired CMIMO transmission system based on the multimode transmission line based on the channel matrix and a theory of a wired CMIMO signal transmission method based on the multimode transmission line.
