基于公平性对偶理论的多小区下行协同波束成形算法
Multi-cell downlink coordinated beam forming algorithm based on fairness duality theory
摘要
Abstract
With the goal to optimize the multi-cell downlink beamforming based on the criterion of the worst-user rate maximization, the Lagrangian duality theory was first used to derive a virtual multi-cell uplink optimization problem that was dual to the primal multi-cell downlink beamforming optimization problem. Base on that, an iterative algorithm was developed to solve the virtual uplink problem by combining the methods of bisection search and geometric programming. Then, the primal multi-cell downlink coordinated beamforming optimization problem could be solved by converting the solution of the virtual uplink problem to the downlink. Simulation results demonstrate that, in contrast to the existing co-ordinated beamforming schemes, the proposed scheme achieves better performance in terms of both the worst-user rate and the rate per energy (RPE).关键词
