METHOD AND DEVICE FOR TRANSMITTING DATA Russian patent published in 2019 - IPC H04B7/08 

FIELD: electrical communication engineering.

SUBSTANCE: invention relates to communication engineering and can be used in wireless communication systems. To this end, method includes steps of modulating information bits to be transmitted according to a lower-order signal constellation and generating lower-order modulation symbols 4m; multiplying the precoding matrix Q by a column vector including each four lower order modulation symbols from the lower order modulation symbols 4m, to obtain 4m to be transmitted upper order modulation symbols corresponding to upper order signal constellation; and transmitting, respectively, 4m to be transmitted upper-order modulation symbols on different carriers of two antennae. Upper order modulation symbols to be transmitted include some or all information bits to be transmitted. Therefore, the same signal can be transmitted simultaneously on different carriers of multiple antennas.

EFFECT: technical result consists in improvement of efficiency of data transmission.
