Covert communication in visible light wireless mobile systems based on NOMA
为了提升可见光移动通信系统的隐蔽传输性能,采用随机发送功率策略来增加监测者的检测不确定程度,构建了联合约束条件下的有效隐蔽速率最大化问题,基于图解法获得了最优发光二极管(LED)发射机发送功率分配比与最优无人机位置,并设计了仿真实验.仿真结果验证了所提方案可以显著提升基于非正交多址接入的可见光移动通信中隐蔽用户的有效隐蔽速率.
In order to improve the covert transmission performance of visible light mobile communication systems,a random transmission power strategy was adopted to increase the detection uncertainty of monitors.An effective covert rate maximization problem under joint constraint conditions was constructed.Based on graphical methods,the optimal transmission power alloca-tion ratio of light emitting diode(LED)transmitters and the optimal drone position were obtained,and simulation experiments were designed.The simulation results have verified that the proposed scheme can significantly improve the effective concealment rate of covert users in visible light mobile communication based on non orthogonal multiple access.
