1. A data transmission device comprising:
a transmitter that transmits a data-carrying signal over a transmission medium having waveguide properties and supporting a plurality of waveguide modes, the transmitter comprises a precoder that precodes a signal for transmission across a plurality of antennas and excites a first waveguide mode within the plurality of waveguide modes;
the plurality of antennas transmits the precoded signal onto the transmission medium based on a training method that transmits a plurality of signals through the plurality of antennas to determine precoder parameters;
wherein the training method providing a plurality of channel response measurements across a plurality of insertion angles into the signal-carrying media, wherein further frequencies, amplitudes and phases of the concurrently transmitted signals, the plurality of insertion angles into the signal-carrying media, amplitudes and phases being defined by a precoder coefficient matrix; and
wherein the transmission medium comprises a set of waveguides that have been formed in gaps between two or more wires to transmit electromagnetic waves, wherein at least a portion of the surfaces of the two or more wires serve as waveguide boundaries.
