FIELD: information technologies.
SUBSTANCE: transmitter sends at least two packets of data via two or more antennas. If at least one of data packets has not been transmitted successfully, transmitter repeatedly sends data packets, re-ordering data packets by method of orthogonal expansion. Transmitter may repeatedly send only unsuccessfully transmitted data packet together with new data packet, which replaces successfully transmitted data packet. Unsuccessfully transmitted data packet may simply be repeated without change in its format. When only unsuccessfully transmitted data packet is transmitted together with the new data packet, transmissions may be combined for simultaneous recovery of repeatedly transmitted data packet and new data packet.
EFFECT: method improvement.
