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…
