Abstract
A method is provided for transmitting a digital signal via n transmit antennas, wherein n is strictly greater than 2. The method includes combining with a source data vector n vectors to be transmitted respectively by each of the transmit antennas by a coding matrix <I>M</I> with a yield equal to 1, using reference symbols known to at least one receiver whereby it is able to estimate at least three transmission channels corresponding respectively to each of the transmit antennas. The coding matrix <I>M</I> applies a mathematical transformation to the reference symbols prior to the transmission thereof.
