摘要：
A joint optimization problem of power control and beamforming for multiple input multiple output (MIMO)-orthogonal frequency division multiplexing (OFDM) system with more realistic interference model was proposed. Then a two-stage scheme based on dual of uplink-downlink and standard interference mapping theory was given to solve this problem, which is proved to be rigorously convergent. Simulations show that the proposed scheme converges faster in multiple-antenna cases and the proposed algorithm outperforms the traditional ones in terms of power saving. © 2018, Editorial Department of Journal of Beijing University of Posts and Telecommunications.
