On DoF of Active RIS-Assisted MIMO Interference Channel with Arbitrary Antenna Configurations: When Will RIS Help?
Shuo Zheng, Bojie Lv, Tong Zhang +4
An active reconfigurable intelligent surface (RIS) has been shown to be able to enhance the sum-of-degrees-of-freedom (DoF) of a two-user multiple-input multiple-output (MIMO) inte…

Secure Rate-Splitting for MIMO Broadcast Channel with Imperfect CSIT and a Jammer
Tong Zhang, Dongsheng Chen, Na Li +3
In this paper, we investigate the secure rate-splitting for the two-user multiple-input multiple-output (MIMO) broadcast channel with imperfect channel state information at the tra…
