Realistic Secrecy Outage Performance for Underlay Cognitive Radio Networks Using MIMO Systems with EH and TAS

EasyChair Preprint 5123

Abstract

In this paper, the physical layer secrecy outage performance of Multiple Input Multiple Output (MIMO) secondary nodes is studied. The proposed model is assumed to operate in underlay Cognitive Radio Network (CRN) that  contains a primary node with a single antenna. Active eavesdropper is also assumed to present in our model. Furthermore, Transmit Antenna Selection (TAS) scheme is applied at the secondary transmitter that has a suitable battery to charge the collected Radio Frequency (RF) energy broadcasted from the primary transmitter to improve both energy and spectral efficiencies. We achieved the secrecy outage performance of the secondary system and derived exact closed-form expression for the secrecy outage performance. The numerical results show that when the number of the antenna at source and/or destination increases, the secrecy outage performance of the system can be improved.
