摘要

缓存辅助多天线中继技术可以为5G通信系统提供广域覆盖范围，并且有效改善系统的吞吐率性能。研究了一个三节点多天线缓存辅助中继系统，提出了最大化系统平均吞吐率的最佳缓存辅助中继策略，即联合自适应链路选择以及功率分配方案。分析结果表明，最佳的链路选择方案仅依赖于当前的瞬时信道状态信息以及相关链路的信道统计信息，而最佳功率分配方案是对发送的数据流进行等功率分配。仿真结果表明，相对于无缓存辅助的MIMO中继系统，缓存的引入能够显著改善中继系统的吞吐率。此外，MIMO技术的引入还能够获得多天线所带来的复用增益，进一步改善缓存辅助中继系统的吞吐率。

Abstract

Buffer-aided multiple-antenna relay technology can provide the 5G communication system with wide coverage

and improve the system throughput performance effectively.A three-node multiple-antenna buffer-aided relay system was investigated and thus an optimal buffer-aided relay strategy

namely joint adaptive link selection and power allocation protocol

which maximizes the average throughput of system was proposed.The analytical results indicate that the optimal link selection policy depends only on the current instantaneous channel state information and the statistical channel information of related links

and the optimal power allocation scheme has equal power allocation for the transmitted data flows.The simulation results show that buffer used in relay could significantly improve the throughput of relay system compared to the relay system without buffer.In addition

the MIMO technique can achieve the multiplexing gain by multiple antennas

and then improve the throughput of buffer-aided relay system further.
