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...
In this context, an RIS-assisted ISAC-UAV network can significantly enhance the quality of aerial service scenarios. This study aims to solve the sum-rate maximization problem while achieving the target detection signal-to-noise ratio (SNR) by jointly optimizing the transmit, beamforming, and RIS...

The proposed system leverages an SR, assisted by a reconfigurable intelligent surface (RIS), to enhance primary communication while enabling secondary data transmission through backscattering. Furthermore, a full-duplex base ...
Specifically, we propose a secure ISAC system supported by a UAV-mounted RIS, where an ISAC base station (BS) facilitates secure multi-user communication while simultaneously detecting potentially malicious radar targets. Our goal is to improve parameter estimation performance, measured by the Cramér...

In this paper, we consider an integrated sensing and communications system assisted by a reconfigurable intelligent surface (RIS). A small number of sparsely placed active sensors are applied in the RIS to perform effective channels and, thereby, enable optimized beamforming for both communications ...
