In intelligent reflecting surface (IRS)-aided multiple-input multiple-output (MIMO) systems,
the IRS can be utilized to suppress the information leakage towards malicious terminals …

This work studies secure transmission in intelligent reflecting surface (IRS)-assisted MIMO
systems when an active eavesdropper is available in the network. We consider a scenario in …

As an effective way to enhance the physical layer security (PLS) for the broadcast channel
(BC), regularized zero-forcing (RZF) precoding has attracted much attention. However, the …

Intelligent reflecting surfaces (IRSs) enable multiple-input multiple-output (MIMO)
transmitters to modify the communication channels between the transmitters and receivers …

Recently, a hybrid analog-digital architecture has been proposed for multiuser MIMO
transmission in the millimeter-wave spectrum using reflect-arrays. The architecture exhibits …

Using intelligent reflecting surfaces (IRSs), wireless propagation channels can be
manipulated such that information leakage to eavesdropping terminals in a multiple-input …

Joint user selection and precoding in multiuser MIMO settings can be interpreted as group
sparse recovery in linear models. In this problem, a signal with group sparsity is to be …
