Abstract:
1. A method for data transmission, comprising: obtaining, by a transmitter, channel information H obtaining, by the transmitter, one or more control vectors corresponding to one or more receivers according to the channel information; modulating, by the transmitter, data to be transmitted by one-dimensional modulation to obtain modulated symbols; processing, by the transmitter, the modulated symbols and the control vectors to obtain transmitted data of each antenna; and transmitting, by the transmitter, the transmitted data to the one or more receivers so that the one or more receivers receive the transmitted data in a predetermined spatial direction of received symbols, wherein and H lΣ =[Re(H l )Im(H l )] or H lΣ =[Im(H l )−Re(H l )], H l is the state information of the channel between the transmitter and the l th receiver.
