Abstract

Different with the passive wireless eavesdropping technique in traditional wireless communications, this paper studied proactive eavesdropping technology at the physical layer for legitimate eavesdropper to monitor the communication between suspicious users. It equipped consider a multiple-input single-output(MISO) system model where the suspicious transmitter and legitimate jammer with multi antennas, and equipped the suspicious receiver and legitimate eavesdropper with single antenna, if the channel gain of the suspicious communication link was stronger than that of the eavesdropping link, the legitimate jammer controled the communication rate of the suspicious users via jamming them, in order for the legitimate eavesdropper to correctly decode the eavesdropped information. Considering two cases that the jammer could or couldn't interference on the legitimate eavesdropper, respectively, it designed the optimal interference signal and power control for the legitimate jammer to maximize the eavesdropping rate. Simulation results show that the proposed interference design method for the jammer in different application scenarios has better eavesdropping performance than the existing two benchmark methods.
