    摘要:

    为了提升非正交多址接入(Non-Orthogonal Multiple Access,NOMA)协作传输系统的安全性能,本文研究了一种基于NOMA双用户协作传输策略的窃听系统模型,并分别推导了此模型下的遍历安全速率和安全中断概率的闭式表达式。仿真结果表明,当存在强解码能力的窃听节点时,本文提出的协作联合接收策略与传统NOMA协作传输策略以及直连策略相比,遍历安全速率最大提升了0.281 bps·Hz-1和0.937 bps·Hz-1,安全中断概率最大降低了2.53dB和3.08dB。

    Abstract:

    In order to improve the security performance of the non-orthogonal multiple access cooperative transmission system, this paper studies an eavesdropping system model based on NOMA dual-user cooperative transmission strategy, and derives the closed-form expression of ergodic secrecy rate and secrecy outage probability under this model respectively. The simulation results show that when existing an eavesdropping nodes with strong decoding capabilities, compared with the traditional NOMA cooperative transmission strategy and direct link strategy, the cooperative joint receiving strategy proposed in this paper has a maximum increase of 0.281 bps·Hz-1 and 0.937 bps·Hz-1 in ergodic secrecy rate, and a maximum decrease of 2.53dB and 3.08dB in secrecy outage probability.
