可以预见的是,RIS-assisted ISAC会是一个非常有意思的研究课题,但可能需要研究者们想一些这种场景下“独特”一点的研究问题,例如ISAC基站-Target没有LoS链路,以及多跳下对Target感知时候感知性能指标的计算方法,还有RIS-assisted双站感知下,利用RIS对于ISAC基站的杂波抑制等。 趁着2nd IEEE JC&S卡住没声来更一波,今天...

Since this problem is a nonconvex combinatorial optimization problem, we solve it by alternating optimization, and propose RIS-assisted MIMO secure communication schemes based on fixed and dynamic subarray partition respectively. In fixed subarray partition scheme, the closed expressions of the optimal ...
In this paper, we study reconfigurable intelligent surface (RIS)-assisted simultaneous legitimate monitoring and jamming techniques for industrial environments, so that egitimate monitor (LM) and legitimate jammers (LJs) can sustainably monitor and interfere with suspicious communications with minimum transmi...
