1. method that is used for transmitting data (S) via radio,-wherein will be divided into the frequency band of a plurality of subcarriers and a plurality of antenna (TX1, TX2, TX3) is used for transmission,-wherein described data (S) are divided into number corresponding to the number of described a plurality of subcarriers, treat respectively element (S1, S2, S3) by each antenna (TX1, TX2, TX3) transmission,-wherein each element (S1, S2, S3) is distributed to each subcarrier that is used to transmit at each antenna (TX1, TX2, TX3),-wherein at least two antennas (TX1, TX2, TX3) transmit different elements (S1, S2, S3) at least one subcarrier,It is characterized in that,-in OFDM modulation (OFDM) before, make specific the multiplying each other of each element (S1, S2, S3) and antenna with the specific factor of element at each antenna (TX1, TX2, TX3).
