摘要

针对基于合作非正交多址(NOMA)的网络,提出了一种先选择天线后选择中继的方案(ASRS)。所提出的工作选择天线以最大化较差信道条件用户的瞬时速率,同时提供良好的服务质量(QoS)。针对不同的天线配置,绘制了所提出方案的中断概率性能,同时随着天线数量和可用中继的变化,SNR和距离也会发生变化。考虑到三个不同的密度区域,还讨论了拟议工作的公平因素。将所提出的方案与文献中的新方案在平均和速率和平均能量效率方面进行了比较,以表明其优越性。

Evaluation of antenna and relay scheme for cooperative non-orthogonal multiple access

Evaluation of antenna and relay scheme for cooperative non-orthogonal multiple access

An antenna selection followed by a relay selection scheme (ASRS) is proposed for cooperative non-orthogonal multiple access (NOMA)-based network. The proposed work selects an antenna to maximise the instantaneous rate of poor channel condition users while providing good quality of services (QoS). The outage probability performance of the proposed scheme is plotted for different antenna configuration while varying the SNR and distance with variable number of antennas and available relays. The fairness factor of the proposed work is also discussed, considering three different density areas. The proposed scheme is compared with novel schemes in literature for average sum rate and average energy efficiency to show its superiority.
