FIELD: physics.
SUBSTANCE: transmitting object with antenna set conveys data to receiving object with one antenna or antenna set, using (1) control mode for a data transmission direction data direction to receiving object or (2) pseudorandom transmission mode (PRTS) for randomising active channels related to subband data transmission. PRTS mode can be used for transmission separation and spacial expansion. Transmission separation is ensured with transmitting object using different pseudorandom vectors of subband control and the same vector of control of the whole package for each subband. Spacial expansion is enabled with transmitting object using different pseudorandom vectors of subband control and different vectors of control of the whole package for each subband.
EFFECT: improved reliability of data transmission.
