Abstract

The present invention proposes an equivalent channel matrix generation method, precoding method, device, equipment, and medium, which are applied to an antenna array, and the antenna array includes a plurality of antenna panels, wherein the equivalent channel matrix generation method includes : Obtain the channel response matrix based on the pilot sequence sent by the user; obtain the simulated beamforming matrix from the preset codebook according to the tree topology relationship, the tree topology relationship is generated based on the number of antenna panels; according to the A channel response matrix and the simulated beamforming matrix generate an equivalent channel matrix. The invention indirectly optimizes the condition number of the equivalent channel matrix through the tree topological relationship, without obtaining singular values, and the optimization of the equivalent channel matrix is ​​more convenient.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method for generating an equivalent channel matrix, a precoding method, a device, equipment and a medium. Background technique [0002] A large-scale multi-panel MIMO (Multi Input Multi Output, multiple input multiple output) antenna array usually has two levels, such as figure 1 As shown, 1 is an antenna panel integrated with multiple sub-antennas, and the antenna panel is used to realize analog beamforming; 2 is an antenna panel array composed of multiple antenna panels, and the antenna panel array provides multiplexing gain. Compared with the traditional all-digital MIMO system, the multi-panel MIMO antenna array can be regarded as a full-digital MIMO system composed of configurable antennas. Each antenna panel is a configurable antenna. By changing the phase shift value, the antenna can be adjusted How the panel radiates. The form of the hybrid precoding matrix F based o...
