On the Closed-Form Solution for Robust Adaptive Beamforming
Licheng Zhao, Rui Zhou, Wenqiang Pu
In this paper, we consider the classical robust adaptive beamforming (RAB) problem. Conventionally, this problem is solved either with an off-the-shelf solver like MOSEK or through…
Radio Map Estimation via Latent Domain Plug-and-Play Denoising
Le Xu, Lei Cheng, Junting Chen +2
Radio map estimation (RME), also known as spectrum cartography, aims to reconstruct the strength of radio interference across different domains (e.g., space and frequency) from spa…
An Efficient and Globally Optimal Algorithm for Nonconvex QCQP with One Equality Constraint
Licheng Zhao, Rui Zhou, Wenqiang Pu
In this paper, we concentrate on a particular category of quadratically constrained quadratic programming (QCQP): nonconvex QCQP with one equality constraint. This type of QCQP pro…
Leveraging LLM Agents for Automated Optimization Modeling for SASP Problems: A Graph-RAG based Approach
Tianpeng Pan, Wenqiang Pu, Licheng Zhao +1
Automated optimization modeling (AOM) has evoked considerable interest with the rapid evolution of large language models (LLMs). Existing approaches predominantly rely on prompt en…
Hybrid Data-Driven SSM for Interpretable and Label-Free mmWave Channel Prediction
Yiyong Sun, Jiajun He, Zhidi Lin +3
Accurate prediction of mmWave time-varying channels is essential for mitigating the issue of channel aging in complex scenarios owing to high user mobility. Existing channel predic…
