Power distribution method based on millimeter wave communication in super-large scale MIMO system

The invention provides a power distribution method based on millimeter wave communication in a super-large-scale MIMO (Multiple Input Multiple Output) system, which comprises the following steps that: firstly, a system model for downlink transmission between a super-large-scale antenna array and a plurality of single-antenna users is constructed, and a base station uses millimeter waves to transmit signals; secondly, grouping the users according to the distribution of the visual areas of the users; then, the base station side adopts a zero-forcing precoding scheme according to the channel state information; and finally, designing an optimal sending power distribution scheme for all users. According to the method, the spatial non-stationary characteristic of the super-large-scale MIMO is utilized, the total transmission rate of the system under the overlapping and non-overlapping scenes of the visual areas of the user groups is effectively improved, and the method has guiding significance for deployment of the
