… The IRs are served with best-effort secrecy … artificial noise (AN) aided transmission strategy.
With the new strategy, we study the optimal resource allocation for the weighted sum secrecy …

… level of secrecy. In this paper, we consider the additional secrecy enhancement with artificial
noise and secrecy … Specifically, we derive the secrecy transmission rate and investigate the …

… statistical channel state information of the eavesdropper is available. We consider transmitting
some artificial noise (AN) along with the information-bearing signal to improve secrecy. To …
