Covert Cooperative Jamming Aided Secure Wireless Communication with Channel Inversion Power Control

In this work, we explore the secure wireless communication with a covert cooperative jammer (CCJ) under the supervision of an intelligent eavesdropper. At first time, we construct the framework of the covert jamming hidden by the channel uncertainty brought by the channel inversion power control (CIPC) technology at the transmitter. Then, we characterize the jamming covertness and communication security by the detection error probability and the secrecy throughput (ST), respectively. At last, we optimize the CIPC constant and the jamming transmit power to maximize ST under the constraint of jamming covertness. Due to the additional channel uncertainty caused by CIPC, the numerical results show that the proposed CIPC scheme can achieve larger ST, compared with the conventional scheme with the constant transmit power (CTP).
