Abstract
This paper studies physical layer security of a three node multicarrier network with a source node, a destination node and a full-duplex proactive eavesdropper who sends jamming signals for improving its eavesdropping performance. The problem of transmit power allocation for minimizing the average secrecy outage probability on all subcarriers is investigated under the assumptions that the channel state information (CSI) related to the eavesdropper is perfectly known and only channel distribution information (CDI) is known. Algorithms are proposed for the optimization problem and are shown to greatly outperform the benchmark algorithms.
