摘要翻译：
认知无线电(CR)和非正交多址(NOMA)是下一代无线通信系统中两种有前途的技术。NOMA CR网络(CRN)的安全性是一个重要而又缺乏研究的问题。本文研究了一种依靠无线信息和功率同时传输的多输入单输出NOMA CRN。为了提高主次网络的安全性，提出了一种人工噪声辅助的协同干扰方案。与已有的大多数工作不同的是，在一个实际的非线性能量收集模型下，提出了一个功率最小化问题。提出了一种基于半定松弛和逐次凸逼近的次优方案来求解该问题。仿真结果表明，所提出的协同干扰方案能够有效地实现安全通信，NOMA在功耗方面优于传统的正交多址接入。

英文摘要：
  Cognitive radio (CR) and non-orthogonal multiple access (NOMA) are two promising technologies in the next generation wireless communication systems. The security of a NOMA CR network (CRN) is important but lacks of study. In this paper, a multiple-input single-output NOMA CRN relying on simultaneous wireless information and power transfer is studied. In order to improve the security of both the primary and secondary network, an artificial noise-aided cooperative jamming scheme is proposed. Different from the most existing works, a power minimization problem is formulated under a practical non-linear energy harvesting model. A suboptimal scheme is proposed to solve this problem based on semidefinite relaxation and successive convex approximation. Simulation results show that the proposed cooperative jamming scheme is efficient to achieve secure communication and NOMA outperforms the conventional orthogonal multiple access in terms of the power consumption.
