1. Method of transmission of at least a data packet by several transmission antennas adapted 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.

Abstract
In order to improve the quality of transmission and reception of data packets, the method of transmission using several antennas comprises:
- an encoding of a first data packet into a first encoded block;
- a mapping of first transmission frequency channel to a first set comprising at least a transmission antenna;
- a mapping of second transmission frequency channel to a second set comprising at least a transmission antenna, the first transmission frequency channel being different of the second transmission 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.
The method of reception comprises a mapping of different frequency channel to reception antennas.
