Abstract
In this paper, cooperative jamming in the multiantenna two-way relaying wiretap system is investigated. Under the assumption that all the channel state information related to the eavesdropper is unknown at legitimate nodes, and the jamming signals generated by the two source nodes can not be shared with each other, the precoding vectors for the user and jamming signals at each source node are designed. Additionally, the power allocation between the user and jamming signals at each source node is also discussed. Simulation results are given to verify the proposed cooperative jamming design.
