Secure Transmission in mmWave NOMA Networks With Cognitive Power Allocation

IEEE Access, 2019
Millimeter wave (mmWave) and non-orthogonal multiple access (NOMA) are two key technologies for future wireless networks. In this paper, secure communication in mmWave NOMA networks based on cognitive power allocation scheme is studied by preferentially ...

Outage probability of selective decode and forward relaying with secrecy constraints

CoRR, 2011
We study the outage probability of opportunistic relay selection in decode-and-forward relaying with secrecy constraints. We derive the closed-form expression for the outage probability. Based on the analytical result, the asymptotic performance is then investigated. The accuracy of our performance analysis is verified by the simulation results.

On the Optimum Secrecy Outage Probability and Ergodic Secrecy Rate over Wireless Channels

We study the secrecy of wireless channels in the presence of an eavesdropper, where the channels are random and the transmitter only has knowledge of the channel statistics. We investigate the optimal input distribution with respect to several secrecy metrics: the Secrecy Outage Probability (SOP), defined as the probability that the coding rate $r ...
