Abstract:
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.
为了提高无线传输的安全与可靠性折中性能, 提出了一种基于联合干扰与用户的调度机制.首先, 在传输时隙中, 具有最大瞬时信道容量的用户节点会被选择与基站进行数据传输;然后, 当用户节点与基站进行数据传输时, 干扰节点会被用于发送人工噪声信号, 以干扰窃听节点窃听用户与基站间的数据传输.仿真结果表明, 增加用户数目可以提高所提出机制的安全与可靠性折中性能.此外, 与传统的轮询调度及纯粹的用户调度这2种机制相比, 该机制能够取得更好的安全与可靠性折中性能, 尤其是在主信道与窃听信道增益比较低时, 该机制还能够确保安全传输.
