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 ...

Robust Power Allocation and Outage Analysis for Secrecy in Independent Parallel Gaussian Channels

, 2016
This letter studies parallel independent Gaussian channels with uncertain eavesdropper channel state information (CSI). First, we evaluate the probability of zero secrecy rate in this system for 1) given instantaneous channel conditions and 2) a Rayleigh
