摘要： A multi-antenna codebook selection modulation method for solving weak scattering is provided by the present invention. The method obtains higher diversity gain from a combination of multi-antenna codebook pre-coding and a rotation modulation solution by designing a new codebook selection rule. The present invention employs a design solution of designing a higher-order modulation diversity and space interleaver to obtain the higher diversity gain. In addition, the number of transmission antennas and the number of rotation modulation dimension can be set arbitrarily. However, the present invention takes the number Nt of transmission antennas to be equal to the number D of rotation modulation dimension in order to obtain higher diversity gain. In this way, the method evenly disperses signals of each dimension after D-dimensional rotation to each antenna through space interleaving technique, so that the signals of each dimension suffer different fading, thus enabling space diversity gain. With the present invention, the data of a transmitting end are pre-coded by using a channel value estimated for an ideal channel.
