Abstract :
This paper presents a probabilistic framework for physical layer secrecy of MIMO communications when the eavesdroppers channels and locations are unknown and modeled by Rayleigh fading and a Poisson point process, respectively. We first quantify the gain in probability of secrecy when using beamforming. Then, we study the case where, in addition to beamforming, artificial noise generation is employed to confuse the eavesdroppers.
