Abstract: Provided is a vector selection modulation-based multi-antenna transmission method, including: for a group of data to be transmitted, using part of bit information in the group of data to select a weight corresponding to the group of data from K preconfigured weights; and performing constellation mapping modulation on residual bit information in the group of data, and using the selected weight corresponding to the group of data to weight the group of data after the constellation mapping modulation, wherein, the K is a natural number. Based on the method of the present document, the spectrum efficiency of the system can be greatly improved under the condition without adding a transmission antenna.
