摘要
In this paper, we consider a D2D communication scenario underlaying an existing cellular network while there exists a malicious user which wants to eavesdrop the transmitted information from the BS to cellular user, and also between D2D pair. Sharing the same frequency band, both the cellular link and D2D pair produce interference on each other. Although this interference is viewed harmful to both of them, it will be useful for distracting the eavesdropper. Therefore, in this situation, D2D communication operates as friendly jammer for cellular network. We aim to maximize the secrecy rate of the whole network. The problem is solved using DC programming Numerical results evaluate our proposed scheme.
