FIELD: physics, communication.
SUBSTANCE: invention is related to communication systems, namely to methods for data transmission in communication system with multiple antennas, which uses multiplexing with orthogonal frequency division (OFDM). Result is achieved by the fact that transmitting object with multiple antennas transmits data to receiving object with multiple antennas, using controlled mode for direction of data transmission to receiving object or mode of pseudorandom control (PRTS) for randomisation of efficient channels, which exist for data transmission in subranges. PRTS mode may be used for realisation of separation in transmission or spatial expansion. For separation in transmission transmitting object uses various vectors of pseudorandom control by subranges used for data transmission, but one and the same control vector by packet for each subrange. It is not required for receiving object to have information about vectors of pseudorandom control or to perform any kind of special processing. For spatial expansion transmitting object uses different vectors of pseudorandom control by subranges and various control vectors by packet for each subrange.
EFFECT: provision of high extent of separation.
