For comparison, we also analyze the case that instead of the NOMA technique, the orthogonal multiple-access (OMA) is utilized by the transceivers. The simulation results show that when the relay node is closer to one of the transceivers, the NOMA-TWRN outperforms its OMA-based counterpart in...
Numerical results show that (1) the offloading outage behaviors of NOMA-MEC are better than those of time division multiple address (TDMA), (2) the offloading outage performance of paired users under ipCSI is worse than that under pCSI, and (3) the NOMA-MEC system achieves higher throughput...
NOMA-Based LPWA Networks 来自 Springer 喜欢 0 阅读量: 5 作者:G Gupta,R Van Zyl 摘要: Non-orthogonal multiple access (NOMA) is used in the uplink for LPWAN for providing services to users or nodes requiring a different set of services. The LoRa nodes usually suffer from inter-cluster and...
In this paper, we develop a non-orthogonal multiple access (NOMA)-based two-way relay network with secrecy considerations, in which two users wish to exchange their NOMA signals via a trusted relay in the presence of single and multiple eavesdroppers. To ensure secure communications, the relay ...
(MAB) algorithms can be used. However, in general, it is difficult to analyze the performance of MAB algorithms in the setting due to the interaction of DDs. Thus, in this paper, instead of analyzing MAB algorithms, we formulate an evolutionary game of DDs in NOMA-based IoT networks and ...
Thus, NOMA can be naturally adopted by the MEC systems to improve the offloading performance. In this paper, we consider a NOMA-based multi-access MEC system with multiple MEC servers and multiple users. It is assumed that each user has multiple computation tasks, where each task shall be ...
The spectral efficiency of the visible light communication system can be enhanced by using the non-orthogonal multiple access (NOMA) scheme. In this paper, we propose a deep Q network (DQN) framework-based power allocation scheme that maximizes the sum rate of a NOMA-based cellular VLC network...

In NOMA-based F-RANs, radio subchannels occupied by remote radio heads (RRHs) can be reused by fog access points (F-APs) and power domain NOMA technique is applied for the link from F-APs to fog user equipments (FUEs). In this paper, an energy efficiency (EE) maximization problem ...
