Multi-Antenna Towards Inband Shift Keying
Ralf R. Müller
We propose a new continuous phase frequency shift keying that is particularly suited for multi-antenna communications when the link budget is critical and beam alignment is problem…
Analysis of Sparse Recovery Algorithms via the Replica Method
Ali Bereyhi, Ralf R. Müller, Hermann Schulz-Baldes
This manuscript goes through the fundamental connections between statistical mechanics and estimation theory by focusing on the particular problem of compressive sensing. We first…
A Novel Antenna Placement Algorithm for Compressive Sensing MIMO Radar
Bastian Eisele, Ali Bereyhi, Ingrid Ullmann +1
In colocated compressive sensing MIMO radar, the measurement matrix is specified by antenna placement. To guarantee an acceptable recovery performance, this measurement matrix shou…
How Should IRSs Scale to Harden Multi-Antenna Channels?
Ali Bereyhi, Saba Asaad, Chongjun Ouyang +3
This work extends the concept of channel hardening to multi-antenna systems that are aided by intelligent reflecting surfaces (IRSs). For fading links between a multi-antenna trans…
Channel Hardening of IRS-Aided Multi-Antenna Systems: How Should IRSs Scale?
Ali Bereyhi, Saba Asaad, Chongjun Ouyang +3
Unlike active array antennas, intelligent reflecting surfaces (IRSs) are efficiently implemented at large dimensions. This allows for traceable realizations of large-scale IRS-aide…
Designing IRS-Aided MIMO Systems for Secrecy Enhancement
Saba Asaad, Yifei Wu, Ali Bereyhi +3
Intelligent reflecting surfaces (IRSs) enable multiple-input multiple-output (MIMO) transmitters to modify the communication channels between the transmitters and receivers. In the…
