Embodiment 1
[0061] Such as figure 1 As shown, the present application provides a millimeter-wave MIMO antenna and hybrid beamforming optimization method, the method includes the following steps:
[0062] Step S1, obtaining a training sample set.
[0063] The training sample set includes the channel matrix set as the input data set, and the data set D as the antenna selection convolutional neural network training AS and as a dataset D trained by a hybrid beamforming convolutional neural network RF .
[0064] Let the input data of the network be N R ×N T ×3,N T is the number of antennas at the transmitter, N R is the number of antennas at the receiving end, 3 means 3 channels, that is, c=3 channels.
[0065] To enrich the input training sample set, we generate NL realized channel matrices, where N different channel matrices are generated with different user positions and channel gains, each channel matrix is for L c different number of clusters generated, in addition, for L n A r...
