Abstract
Considering that a legitimate full-duplex monitor aims to intercept the suspicious wireless transmission, we study the robust jamming design problem where imperfect channel state information is assumed. We model channel estimation errors as deterministically-bounded and define the successful monitoring event as that the signal-to-interference-plus-noise ratio (SINR) at the legitimate monitor is higher than the SINR at the suspicious receiver. To increase the worst-case probability of successful monitoring, we propose a robust proactive monitoring via jamming scheme. From simulation results, our proposed robust scheme is superior to the non-robust one.
