Wireless Covert Communications Based on Intelligent Reflecting Surface Aided and Artificial Noise Enhanced

  • 摘要: 该文考虑一种智能反射面(IRS)辅助及人工噪声(AN)增强的无线隐蔽通信以提升隐蔽传输性能。首先,分析了Willie的探测性能并给出了总的最小探测错误概率下界表达式。 在此基础之上,构建以最大化有效吞吐量为目标函数,以隐蔽需求和最大AN发射功率为约束的优化问题。该优化问题为非凸的,通常很难直接求解。该文提出基于Dinkelbach方法的交替迭代算法联合设计IRS的反射系数和Alice的发射功率及Bob的AN发射功率。为了降低计算复杂度,进一步提出一种低复杂度算法以获取相应优化变量的解析表达式。仿真结果表明:与无IRS及无AN方案相比,所提方案可以显著提升隐蔽传输性能。
