Benefits of multiple transmit antennas in secure communication: A secrecy outage viewpoint

Zhang, Xi; McKay, Matthew R.; Zhou, Xiangyun


This paper investigates secure multi-antenna transmission in slow fading channels without the eavesdropper's channel state information. The use of multiple transmit antennas enables the transmitter to strengthen the signal reception at the intended receiver while simultaneously confusing the eavesdropper by delivering artificial noise. A recently developed secrecy outage formulation, which can separately measure the quality of service and the level of security, is used to characterize the...[Show more]
