METHOD FOR THE MULTI-ANTENNA TRANSMISSION OF A LINEARLY-PRECODED SIGNAL, CORRESPONDING DEVICES, SIGNAL AND RECEPTION METHOD

摘要

The invention relates to a method for the transmission of a signal formed by vectors, each vector comprising N source symbols to be transmitted, using M transmission antennas, wherein M is greater than or equal to 2. The inventive method comprises the following steps consisting in: linearly precoding the signal using a matrix product of a source matrix formed by vectors that are organised in successive lines by a linear precoding matrix, delivering a precoded matrix; and successively transmitting precoded vectors corresponding to columns of said precoded matrix, the M symbols of each precoded vector being distributed to the M antennas.
