Robust Beamforming for Multiuser MIMO Systems with Unknown Channel Statistics: A Hybrid Offline-Online Framework
Wenzhuo Zou, Ming-Min Zhao, An Liu +1
Robust beamforming design under imperfect channel state information (CSI) is a fundamental challenge in multiuser multiple-input multiple-output (MU-MIMO) systems, particularly whe…
AMBER: An Adaptive Multimodal Mask Transformer for Beam Prediction with Missing Modalities
Chenyiming Wen, Binpu Shi, Min Li +3
With the widespread adoption of millimeter-wave (mmWave) massive multi-input-multi-output (MIMO) in vehicular networks, accurate beam prediction and alignment have become critical…
Ambiguity Function Analysis and Optimization of Frequency-Hopping MIMO Radar with Movable Antennas
Xiang Chen, Ming-Min Zhao, Min Li +3
In this paper, we propose a movable antenna (MA)-enabled frequency-hopping (FH) multiple-input multiple-output (MIMO) radar system and investigate its sensing resolution. Specifica…
Channel Tracking and Prediction for IRS-aided Wireless Communications
Yi Wei, Ming-Min Zhao, An Liu +1
For intelligent reflecting surface (IRS)-aided wireless communications, channel estimation is essential and usually requires excessive channel training overhead when the number of…
Two-Stage Stochastic Optimization via Primal-Dual Decomposition and Deep Unrolling
An Liu, Rui Yang, Tony Q. S. Quek +1
We consider a two-stage stochastic optimization problem, in which a long-term optimization variable is coupled with a set of short-term optimization variables in both objective and…
Stochastic Transceiver Optimization in Multi-Tags Symbiotic Radio Systems
Xihan Chen, Hei Victor Cheng, Kaiming Shen +2
Symbiotic radio (SR) is emerging as a spectrum- and energy-efficient communication paradigm for future passive Internet-of-things (IoT), where some single-antenna backscatter devic…
