摘要：
In order to improve the performance of the security-reliability tradeoff (SRT), a joint jammer and user scheduling (JJUS) scheme is proposed. First, a user with the maximal instantaneous channel capacity is selected to transmit its signal to the base station (BS) in the transmission time slot. Then, when the user transmits its signal to BS, the jammer is invoked for transmitting artificial noise in order to perturb the eavesdropper's reception. Simulation results show that increasing the number of users can enhance the SRT performance of the proposed JJUS scheme. In addition, the SRT performance of the proposed JJUS scheme is better than that of the traditional round-robin scheduling and pure user scheduling schemes. The proposed JJUS scheme can guarantee the secure transmission even in low main-to-eavesdropper ratio(MER) regions. © 2016, Editorial Department of Journal of Southeast University.
