%X This contribution introduces a new transmission scheme for multiple-input multiple-output (MIMO)orthogonal frequency division multiplexing (OFDM) systems. The new scheme is efficient and suitableespecially for symmetric channels such as the link between two base stations or between two antennas onradio beam transmission. The principle is based on the estimation of channel parameters of a pilot datasend by the receiver to the transmitter. Then, the transmitter codes the transmitted signal using theestimated channel parameters to adapt the signal to the channel variations. Conducted Monte-Carlosimulation results show that the proposed scheme has better performance, in terms of bandwidth efficiencyand complexity, compared to the conventional MIMO-OFDM scheme methods in the case of a symmetricchannel.
