上下行链路中非正交多址接入用户匹配及功率算法的改进
摘要
本文通过用户分簇、发送端功率域复用、接收端SIC技术等对非正交多址接入上下行链路进行分析,提出对于多用户共享者相同的通信资源这一现象的用户配对及功率分配优化算法。
this paper analyzes the non-orthogonal multi-access upstream and downstream links through user clustering, power domain multiplexing at the sending end, SIC technology at the receiving end etc. And proposes the user pairing and power distribution optimization algorithm for the phenomenon that multiple users share the same communication resources.
