On Optimal MMSE Channel Estimation for One-Bit Quantized MIMO Systems
Minhua Ding, Italo Atzeni, Antti Tölli +1
This paper focuses on the minimum mean squared error (MMSE) channel estimator for multiple-input multiple-output (MIMO) systems with one-bit quantization at the receiver side. Desp…
IRS-Enhanced Anti-Jamming Precoding Against DISCO Physical Layer Jamming Attacks
Huan Huang, Hongliang Zhang, Yi Cai +3
Illegitimate intelligent reflective surfaces (IRSs) can pose significant physical layer security risks on multi-user multiple-input single-output (MU-MISO) systems. Recently, a DIS…
Block-Level MU-MISO Interference Exploitation Precoding: Optimal Structure and Explicit Duality
Junwen Yang, Ang Li, Xuewen Liao +2
This paper investigates block-level interference exploitation (IE) precoding for multi-user multiple-input single-output (MU-MISO) downlink systems. To overcome the need for symbol…
Secure Short-Packet Transmission with Aerial Relaying: Blocklength and Trajectory Co-Design
Milad Tatar Mamaghani, Xiangyun Zhou, Nan Yang +1
In this paper, we propose a secure short-packet communication (SPC) system involving an unmanned aerial vehicle (UAV)-aided relay in the presence of a terrestrial passive eavesdrop…
RIS-aided Near-Field MIMO Communications: Codebook and Beam Training Design
Suyu Lv, Yuanwei Liu, Xiaodong Xu +2
Downlink reconfigurable intelligent surface (RIS)-assisted multi-input-multi-output (MIMO) systems are considered with far-field, near-field, and hybrid-far-near-field channels. Ac…
Performance Analysis of Finite Blocklength Transmissions Over Wiretap Fading Channels: An Average Information Leakage Perspective
Milad Tatar Mamaghani, Xiangyun Zhou, Nan Yang +2
Physical-layer security (PLS) is a promising technique to complement more traditional means of communication security in beyond-5G wireless networks. However, studies of PLS are of…
