Abstract
Embodiments of the present disclosure disclose a method and an apparatus for determining a precoding matrix, which relate to the field of communications technologies and may improve throughput of a MIMO system and optimize overall system performance, including: determining a rank constraint of a jtransmitting end, where j=1, 2, . . . , K, and K is the total number of transmitting ends in a MIMO system; iteratively calculating an optimal precoding matrix of the jtransmitting end according to a channel matrix from the jtransmitting end to a jreceiving end, an autocorrelation matrix of interference and noise of the jreceiving end, and the rank constraint of the jtransmitting end, where the optimal precoding matrix maximizes channel capacity of a link from the jtransmitting end to the jreceiving end under a circumstance that precoding matrices of other transmitting ends do not change.
