摘要 针对中继辅助通信系统,讨论了多中继并行传输下的优化设计问题,提出了一种简化的线性优化方案,并从多用户分集的角度,在等待服务用户中选择中继协作分集增益较大的用户对其进行服务。这种方案巧妙地减少了由于多中继并行传输所造成的用户间干扰,保持了多中继并行传输引入的空间分集所带来的性能优势,达到了提高系统总吞吐量的目的。 Joint optimization of cooperative relays in MIMO multiple relay aided communication system is discussed in this paper. A simple linear optimization solution is designed and a multi-user scheduling algorithm is proposed. This new algorithm, which chooses the users with larger cooperation diversity gains from waiting list to serve, can reduce inter-user interference caused by parallel transmission of multiple relays, maintain space diversity introduced by parallel transmission of multiple relays and achieve higher throughput of system.
