Abstract
This application provides a precoding method and an apparatus for improving a power utilization of antennas. The method includes: determining a generalized inverse matrix Hof a channel value matrix Hof K users in an miteration in J iteration operations, where m=1, 2, . . . , and J, 1≤J≤M−K+1, and M is a quantity of antennas; selecting, from a set S1based on H, an antenna index nand an update coefficient αcorresponding to n, where S1is a set of n unselected in antenna indexes n of the M antennas until an (m−1)iteration ends; determining a weight matrix Wbased on Hand α; and assigning a row in Wand corresponding to nto a row in a final weight matrix Wand corresponding to n, where Wis to adjust transmit powers of at least J of the M antennas to a preset maximum transmit power P after the J iteration operations end.
