摘要
This paper investigates the performance of a legitimate surveillance system, where a legitimate monitor aims to eavesdrop on a dubious decode-and-forward relaying communication link. In order to maximize the eavesdropping non-outage probability, three different eavesdropping modes are proposed, where the legitimate monitor can adaptively perform eavesdropping or jamming. Optimal jamming power design and exact closed-formed expressions of the eavesdropping non-outage probability for each mode are presented. Numerical results reveal that the eavesdropping mode selection significantly improves the eavesdropping non-outage probability.
