中文摘要：
为了高效实现多点协同下行链路的协同传输,该文基于最大化最小信干噪比准则提出了一种单层迭代分布式协同波束成形算法,并且证明了该算法的全局收敛性;利用该算法中优化波束的特征,进而提出了一种分布式协同用户调度算法。仿真结果表明,所提分布式协同波束成形和用户调度算法可获得明显优于已有算法的最小信干噪比性能,且只需要很少量的基站间信息交互。
英文摘要：
In order to achieve efficient coordination multiple point downlink transmission,a single iteration of distributed collaborative beamforming algorithm is proposed based on the merit of maximizing the minimum SINR,and the global convergence of the proposed algorithm is proven.Furthermore,a distributed coordinated user scheduling algorithm is developed by using characteristics of optimum beam in the proposed algorithm.Simulation results show that the proposed distributed coordinated beamforming and user scheduling algorithm is superior to existing algorithms in term of the minimum user SINR performance,and only a small amount of information exchange between base stations.
