RIS安全
[1]Secrecy Rate Maximization for Intelligent Reflecting Surface Assisted Multi-Antenna Communications(2019)
场景:单用户,单Eve,MISO,信道LOS+RIS
优化变量:W^发射信号空域的自相关(beam?),θ^(RIS)
交替优化,W^前文(相当于beam)有解,θ^分式优化。
[2] Enabling Secure Wireless Communications via Intelligent Reflecting Surfaces(2019)
场景:单用户,单Eve,MISO,信道只有RIS
优化变量:f^beam,θ^(RIS)
交替优化,f^前文(相当于beam)有解,θ^ 元素块下降不理解奇怪/(为什后方法也叫交替?)minorization maximization(或者也可以用SDR)
[3] Secure MIMO Transmission via Intelligent Reflecting Surface(2020)
场景:单用户,单Eve,MIMO,信道只有RIS
优化变量:R^发射信号空域的自相关(beam?),θ^*(Q)(RIS)
minorization maximization
[4] Robust and Secure Wireless Communications via Intelligent Reflecting Surfaces(2020,长文)
场景:多用户,单Eve,双RIS,MIMO,信道只有RIS,考虑CSI误差?
很复杂
[5] Robust Transmission Design for Intelligent Reflecting Surface-Aided Secure Communication Systems With Imperfect Cascaded CSI(2021)
场景:单用户,双Eve,单RIS,MISO,信道只有RIS,AN(人工噪声),考虑RIS到Eve的CSI误差?
优化目标:反而是功率最小化,secret rate是约束
[6] Secure Transmission for Intelligent Reflecting Surface-Assisted mmWave and Terahertz Systems(2020)
场景:单用户,单Eve,单RIS,MISO,信道只有RIS,HBF,θ^离散化
优化变量:w^(HBF)
交替优化,先w,(闭式解)后θ,(1. Charnes-Cooper变换方法(奇妙)+SDR / 2. Element-Wise BCD Algorithm不理解奇怪)
[7] Secure Wireless Communication in RIS-Aided MISO System With Hardware Impairments(2021)
场景:单用户,单Eve,单RIS,MISO,信道LOS+RIS,硬件受损(Tx多了一项和Tx发射功率正比的复高斯,Rx同理)
交替优化,辅助变量,SCA优化 θ,优化beam用SDR
[8] Secure Wireless Communication via Intelligent Reflecting Surface(2019可能是最初的几篇)
场景:单用户,单Eve,单RIS,MISO,信道LOS+RIS
交替优化,先得到w^,Charnes-Cooper变化+SDR得到θ^
[9] Artificial-Noise-Aided Secure MIMO Wireless Communications via Intelligent Reflecting Surface(2020)
场景:单用户,单Eve,单/多RIS,MIMO,信道LOS+RIS,AN可控人工噪声
假设了接收机求MSE等关联目标函数
