Data Transmission System

A data transmission system (1) comprising:

• a data transmission channel (2;
• 21, 22);
• and
• a plurality of transmission and reception units (3);
• and wherein
• the data transmission channel (2;
• 21, 22);
• is an electrical line, which has a rail (4;
• 41, 42);
• that is made of an electrically insulating material and the data transmission channel (2;
• 21, 22);
• has at least one electrical conductor (5), and wherein the at least one electrical conductor (5) runs in a longitudinal direction along a longitudinal axis (6) of the rail (4;
• 21, 42), and wherein a lateral surface of the rail (4;
• 41, 42);
• is surrounded by at least one electrical conductor (5) and/or at least two of the electrical conductors (5) are kept apart from one other by the rail (4;
• 41, 42);
• and, wherein
• the plurality of transmission and reception units (3) are arranged along the rail (4;
• 41, 42), and wherein the plurality of transmission and reception units (3) are each configured to couple an electromagnetic wave into the electrical line or out of the electrical line;
• and
• a coupling apparatus (13) for electromagnetic near-field coupling is arranged between at least one of the plurality of transmission and reception units (3) and the electrical line, and wherein the coupling apparatus (13) has at least two coupling elements (14);
• and wherein each of the at least two coupling elements (14) has an electrical terminal (15), or the coupling apparatus (13) has at least one coupling element (14) that has at least two electrical terminals (15);
• and wherein
• the plurality of transmission and reception units (3) has a unit for MIMO equalization (17) and the plurality of transmission and reception units (3) has a unit for MIMO control (18);
• and wherein
• the unit for MIMO equalization (17) and the unit for MIMO control (18) are in each case connected to the electrical terminals (15) of the coupling elements (14).
