On the Effective Rate of NOMA in Underlay Spectrum Sharing
Vaibhav Kumar, Zhiguo Ding, Mark F. Flanagan
In this paper, we present the delay-constrained performance analysis of a multi-antenna-assisted multiuser non-orthogonal multiple access (NOMA) based spectrum sharing system over…
Secrecy Rate Maximization for Intelligent Reflecting Surface Assisted MIMOME Wiretap Channels
Anshu Mukherjee, Vaibhav Kumar, Le-Nam Tran
Intelligent reflecting surface (IRS) has gained tremendous attention recently as a disruptive technology for beyond 5G networks. In this paper, we consider the problem of secrecy r…
On the Secrecy Rate under Statistical QoS Provisioning for RIS-Assisted MISO Wiretap Channel
Vaibhav Kumar, Mark F. Flanagan, Derrick Wing Kwan Ng +1
Reconfigurable intelligent surface (RIS) assisted radio is considered as an enabling technology with great potential for the sixth-generation (6G) wireless communications standard.…
On the Optimality of the Stationary Solution of Secrecy Rate Maximization for MIMO Wiretap Channel
Anshu Mukherjee, Vaibhav Kumar, Eduard Jorswieck +2
To achieve perfect secrecy in a multiple-input multiple-output (MIMO) Gaussian wiretap channel (WTC), we need to find its secrecy capacity and optimal signaling, which involves sol…
On the Secrecy Rate of Downlink NOMA in Underlay Spectrum Sharing with Imperfect CSI
Vaibhav Kumar, Mark F. Flanagan, Daniel Benevides da Costa +1
In this paper, we present the ergodic sum secrecy rate (ESSR) analysis of an underlay spectrum sharing non-orthogonal multiple access (NOMA) system. We consider the scenario where…
Link-Layer Capacity of Downlink NOMA with Generalized Selection Combining Receivers
Vaibhav Kumar, Barry Cardiff, Shankar Prakriya +1
Non-orthogonal multiple access (NOMA) has drawn tremendous attention, being a potential candidate for the spectrum access technology for the fifth-generation (5G) and beyond 5G (B5…
