Secrecy Outage Probability Analysis for Downlink RIS-NOMA Networks with On-Off Control
Yingjie Pei, Xinwei Yue, Wenqiang Yi +3
Reconfigurable intelligent surface (RIS) has been regarded as a promising technology since it has ability to create the favorable channel conditions. This paper investigates the se…
User-Pair Selection for QoS-Aware Secrecy Rate Maximization in Untrusted NOMA
Sapna Thapar, Deepak Mishra, Ravikant Saini +1
Non-orthogonal multiple access (NOMA) has been recognized as one of the key enabling technologies for future generation wireless networks. Sharing the same time-frequency resource…
A Fine Grained Stochastic Geometry Based Analysis on LEO Satellite Communication Systems
Yanshi Sun, Zhiguo Ding
Recently, stochastic geometry has been applied to provide tractable performance analysis for low earth orbit (LEO) satellite networks. However, existing works mainly focus on analy…
Performance Analysis of Reconfigurable Intelligent Surface Assisted Two-Way NOMA Networks
Ziwei Liu, Xinwei Yue, Chao Zhang +4
This paper investigates the performance of reconfigurable intelligent surface assisted two-way non-orthogonal multiple access (RIS-TW-NOMA) networks, where a pair of users exchange…
Joint Transmit Precoding and Reflect Beamforming Design for IRS-Assisted MIMO Cognitive Radio Systems
Weiheng Jiang, Yu Zhang, Jun Zhao +2
Cognitive radio (CR) is an effective solution to improve the spectral efficiency (SE) of wireless communications by allowing the secondary users (SUs) to share spectrum with primar…
Power Minimization for Multi-cell Uplink NOMA with Imperfect SIC
M. Zeng, W. Hao, O. A. Dobre +2
In this paper, we investigate a multi-cell uplink non-orthogonal multiple access (NOMA) system with imperfect successive interference cancellation (SIC). The objective of the formu…
