Optimal Grouping Strategy for Reconfigurable Intelligent Surface Assisted Wireless Communications
Neel Kanth Kundu, Zan Li, Junhui Rao +3
The channel estimation overhead of reconfigurable intelligent surface (RIS) assisted communication systems can be prohibitive. Prior works have demonstrated via simulations that gr…
MIMO Terahertz Quantum Key Distribution
Neel Kanth Kundu, Soumya P. Dash, Matthew R. McKay +1
We propose a multiple-input multiple-output (MIMO) quantum key distribution (QKD) scheme for terahertz (THz) frequency applications operating at room temperature. Motivated by clas…
Exact Statistical Characterization of Gram Matrices with Arbitrary Variance Profile
Nicolas Auguin, David Morales-Jimenez, Matthew McKay
This paper is concerned with the statistical properties of the Gram matrix , where is a complex central Gaussian ma…
Power Allocation Schemes for Multicell Massive MIMO Systems
Qi Zhang, Shi Jin, Matthew McKay +2
This paper investigates the sum-rate gains brought by power allocation strategies in multicell massive multipleinput multiple-output systems, assuming time-division duplex transmis…
Artificial-Noise-Aided Secure Multi-Antenna Transmission with Limited Feedback
Xi Zhang, Matthew R. McKay, Xiangyun Zhou +1
We present an optimized secure multi-antenna transmission approach based on artificial-noise-aided beamforming, with limited feedback from a desired single-antenna receiver. To dea…
Tomlinson-Harashima Precoding for Multiuser MIMO Systems with Quantized CSI Feedback and User Scheduling
Liang Sun, Matthew R. McKay
This paper studies the sum rate performance of a low complexity quantized CSI-based Tomlinson-Harashima (TH) precoding scheme for downlink multiuser MIMO tansmission, employing gre…
