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…
Symbol-Level Precoding for MU-MIMO System with RIRC Receiver
Xiao Tong, Ang Li, Lei Lei +2
Consider a multiuser multiple-input multiple-output (MU-MIMO) downlink system in which the base station (BS) sends multiple data streams to multi-antenna users via symbol-level pre…
STAR-RIS Enhanced Joint Physical Layer Security and Covert Communications for Multi-antenna mmWave Systems
Han Xiao, Xiaoyan Hu, Ang Li +4
This paper investigates the utilization of simultaneously transmitting and reflecting RIS (STAR-RIS) in supporting joint physical layer security (PLS) and covert communications (CC…
Deep Learning-Based Channel Extrapolation for Pattern Reconfigurable Massive MIMO
Mu Liang, Ang Li
Reconfigurable antennas that can dynamically change their operation state exhibit excellent adaptivity and flexibility over traditional antennas, and MIMO arrays that consist of mu…
Probabilities of Causation with Nonbinary Treatment and Effect
Ang Li, Judea Pearl
This paper deals with the problem of estimating the probabilities of causation when treatment and effect are not binary. Tian and Pearl derived sharp bounds for the probability of…
