no code implementations • 24 Dec 2022 • Si-Nian Jin, Dian-Wu Yue, Yi-Ling Chen, Qing Hu

In this paper, we consider an intelligent reflecting surface (IRS)-aided cell-free massive multiple-input multiple-output system, where the beamforming at access points and the phase shifts at IRSs are jointly optimized to maximize energy efficiency (EE).

Graph-based Matched Field Localization for an Underwater Source

no code implementations • 18 Jan 2021 • Peng Xiao, Lingji Xu, Liya Xu, Jianmin Yang, Qing Hu

Matched Field Processing (MFP) locates the underwater sources by matching the received data with the replica vectors, which could be regarded as a generalized beamformer.
