Long, Hang and Xiang, Wei and Wang, Jing and Zhang, Yueying and Zhao, Hui and Wang, Wenbo (2013) Cooperative jamming and power allocation in two-way relaying system with eavesdropper. In: IEEE 78th Vehicular Technology Conference (VTC 2013 Fall): Connecting the Mobile World, 2-5 Sep 2013, Las Vegas, NV. United States.


The security of the two-way relaying system with an eavesdropper is investigated in this paper. A cooperative jamming and power allocation scheme is proposed to enhance the system secrecy capacity. Both user and pre-defined jamming signals are transmitted by each source node simultaneously. The optimum power allocation between the user and jamming signals at each source node is derived. Our analytical results suggest that the proposed cooperative jamming scheme improves on the system secrecy capacity, especially when the channel gains of the two source-relay links are of large difference. Simulation results in close agreement with analytical results clearly demonstrate the advantage of the proposed cooperative jamming scheme.
