Worst-Case and Covariance-Reconstruction Robust Adaptive Beamforming: Equivalence and Closed-Form Solution
Licheng Zhao, Rui Zhou, Wenqiang Pu +1
Robust adaptive beamforming (RAB) has developed along two separate lines. The worst-case-constrained approach guards against steering vector mismatch with a bounded uncertainty set…
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…
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…
Mixed Max-and-Min Fractional Programming for Wireless Networks
Yannan Chen, Licheng Zhao, Kaiming Shen
Fractional programming (FP) plays a crucial role in wireless network design because many relevant problems involve maximizing or minimizing ratio terms. Notice that the maximizatio…
Optimization of MIMO Device-to-Device Networks via Matrix Fractional Programming: A Minorization-Maximization Approach
Kaiming Shen, Wei Yu, Licheng Zhao +1
Interference management is a fundamental issue in device-to-device (D2D) communications whenever the transmitter-and-receiver pairs are located in close proximity and frequencies a…
