Abstract

This paper is concerned with sum rate maximization problem (program) of coordinated downlink beamforming in multicell multi-antenna wireless networks, which has never been adequately considered in literature due to its computational difficulty. It is shown to be efficiently solved by means of d.c. (difference of two convex functions/sets) programming. The important advantages of our proposed algorithm are: guaranteed convergence, low computational complexity, and excellent performance.
