Security outage probability with antenna selection in Full-duplex system

In this paper, we study the security performance with antenna selection in full-duplex system, where the destination is equiped with mutil-antennas. In our proposed scheme, the destination can combine a subset of “strongest” paths out of available paths from the source, and the others can sends jamming to the eavesdropper. We obtain the closed form expressions of security outage probability. Combining the half-duplex system, the security performance can be improved. With the selected jamming antennas increasing, the security performance is increasing when the SNR is high.
