Patent ID: 8514795

Claim:
Method of transmission of at least a data packet by several transmission antennas configured to transmit a signal, wherein it comprises: an encoding of a first data packet into a first encoded block and a second data packet into a second encoded block; a mapping of first frequency channel to a first set comprising at least a transmission antenna; a mapping of second frequency channel to a second set comprising at least a transmission antenna, the first frequency channel being different from the second frequency channel; a transmission of the first encoded block on the first set of at least a transmission antenna and on the second set of at least a transmission antenna; if quality of reception at first frequency channel is lower than a threshold, a mapping to second frequency channel or third frequency channel different from first frequency channel to the first set comprising at least a transmission antenna; and a transmission of the second encoded block on the first set of at least a transmission antenna and on the second set of at least a transmission antenna.
