FIELD: methods for processing data for distribution during transmission in multi-antenna communication system.
SUBSTANCE: for spatial distribution in multi-antenna OFDM system the transmitter conducts encoding, interleaving and indication of symbols for traffic data to produce data symbols, the transmitter processes each pair of data symbols to produce two pairs of transmitted symbols for transmission through a pair of antennas either (1) in two periods of OFDM symbol for spatial-temporal distribution during transmission, or (2) in two sub-ranges for spatial-temporal distribution during transmission. For data transmission, NT(NT-1)/2 various pairs of antennas are used, where various pairs of antennas are used for adjacent sub-ranges, where NT represents the number of antennas, the system may maintain a set of sizes of OFDM symbols, for various sizes of OFDM symbols, identical circuits are used for encoding, interleaving and modulation to facilitate processing in transmitter and receiver, the transmitter performs OFDM modulation for the stream of transferred symbols for each antenna according to selected size of OFDM symbol, the receiver conducts complementary processing.
EFFECT: ensured spatial distribution.
