FIELD: radio engineering, communication.
SUBSTANCE: invention discloses, in particular, a method in which at least one data symbol stream is received for transmission from a plurality of antennae. Each data symbol stream is scaled with a respective weight coefficient corresponding to the value of transmit power allocated to that stream. The scaled data symbol stream(s) are multiplied with a transmit basis matrix to provide a plurality of transmit symbol streams for the plurality of antennae. The transmit basis matrix (e.g., a Walsh-Hadamard matrix or a DFT matrix) is defined such that each data symbol stream is transmitted from all antennae and each transmit symbol stream is transmitted at full power for the associated antenna.
EFFECT: transmitting a variable number of data symbol streams, transmission diversity for each data symbol stream and enabling full utilisation of the total transmit power of the system and the full power of each antenna.
