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…
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…
Fast Fractional Programming for Multi-Cell Integrated Sensing and Communications
Yannan Chen, Yi Feng, Xiaoyang Li +2
This paper concerns the coordinate multi-cell beamforming design for integrated sensing and communications (ISAC). In particular, we assume that each base station (BS) has massive…
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…
