This letter studied the covert communication with the help of the cognitive jammer over an additive white Gaussian noise (AWGN) channel. The cognitive jammer first senses Alice’s transmission; then, based on its sensing results, it determines whether to transmit the jamming signal. The results showed that the cognitive function of the jammer does help to increase the communication rate of the Alice to Bob link while keeping the eavesdropper, Willie, from detecting the existence of the transmission.
