An information stream of binary symbols is divided into serial packets of N binary symbols. The method further includes serial-parallel conversion of binary symbols in each serial packet and repeating N times the parallel packet thus obtained in order to form a serial-parallel packet of binary symbols. The binary symbols are permuted in the duration interval of each serial-parallel packet, and orthogonal codes generated according to the above binary symbol permutation are then applied. A space-diversity channel is then assigned to each serial group of the serial-parallel packet of coded binary symbols thus obtained. All the serial groups of coded binary symbols, each coded binary symbol having been previously spread by a user spreading code, as well as pilot signals of the corresponding space diversity channels are simultaneously transmitted. The method also involves generating on the reception side a serial packet of soft decisions that corresponds to the serial packet of binary symbols on the transmission side.
