RIS-Assisted Joint Uplink Communication and Imaging: Phase Optimization and Bayesian Echo Decoupling

no code implementations10 Jan 2023 Shengyu Zhu, Zehua Yu, Qinghua Guo, Jinshan Ding, Qiang Cheng, Tie Jun Cui

Achieving integrated sensing and communication (ISAC) via uplink transmission is challenging due to the unknown waveform and the coupling of communication and sensing echoes.

A multi-domain splitting framework for time-varying graph structure

no code implementations29 Sep 2021 Zehua Yu, Xianwei Zheng, Zhulun Yang, Xutao Li

To address the anomaly detection problem for datasets with a spatial-temporal structure, in this work, we propose a novel graph multi-domain splitting framework, called GMDS, by integrating the time, vertex, and frequency features to locate the anomalies.
