Abstract: In this paper, we propose a multi-point joint transmission method for Coordinated Multi-Point (CoMP ) systems. This solution combines space time/frequency coding and precoding with beamforming technology. The multi-path data obtained by space time/ frequency coding and precoding can be mapped by beamforming technology to multiple coordinated nodes for transmission. The signal receiver can also obtain bigger diversity gain and beamforming gain as well through the combination of space time/frequency coding and beamforming. Moreover, precoding and beamforming can help the signals transmitted from separate nodes in CoMP system combine at the receiver, which makes the signals at different layers more independent and obtains beamforming gain.
