FIELD: data transfer.
SUBSTANCE: invention is related to data transfer in communication systems with multiple inputs multiple outputs (MIMO). Available transmission channels are arranged in a number of groups. Each group may include all transmission channels for corresponding natural mode of MIMO channel. Full transmitted power is distributed among groups based on specific power distribution circuit. Random inversion of channels is independent for each selected group. Scale parameter is defined for each selected channel so that all selected channels for definite group could achieve similar quality of received signal, for example, received signal-noise ratio (SNR).
EFFECT: random inversion for channels in each natural mode for achieving high spectral effectiveness by reducing complexity both on transmitter and receiver.
