The present invention provides a dual current emission method and transmitter that can simultaneously transmit two streams in a single radio frequency channel. The method comprises: a first data stream and the modulation transmitter respectively second data flow, the number of the first set of symbols including data flow modulation generated after the symbols of; according to the corresponding relationship between symbols and beamforming preset, select transmit beam corresponding to the first data stream of modulation symbols used; the way to select the symbol representing the first data stream transmitting beam modulation, through beam selection to transmit the first data stream receiver modulated symbols, and uses the beam selection bearing second data stream symbols and modulation, by transmitting beam selection to the receiver transmit second data stream modulated symbols.
