Adaptive Beam Alignment using Noisy Twenty Questions Estimation with Trained Questioner
Chunsong Sun, Lin Zhou
The 6G communication systems use mmWave and MIMO technologies to achieve wide bandwidth and high throughout, leading to indispensable need for beam alignment to overcome severe sig…
Privacy-Resolution Tradeoff for Adaptive Noisy Twenty Questions Estimation
Chunsong Sun, Lin Zhou
We revisit noisy twenty questions estimation and study the privacy-resolution tradeoff for adaptive query procedures. Specifically, in twenty questions estimation, there are two pl…
Resolution Limits of Non-Adaptive 20 Questions Estimation for Tracking Multiple Moving Targets
Chunsong Sun, Lin Zhou, Jingjing Wang +3
Motivated by the practical application of beam tracking of multiple devices in Multiple Input Multiple Output (MIMO) communication, we study the problem of non-adaptive twenty ques…
Over-the-Air Diagnosis of Defective Elements in Intelligent Reflecting Surface
Ziyi Zhao, Zhaorui Wang, Lin Zhou +4
Due to circuit failures, defective elements that cannot adaptively adjust the phase shifts of their impinging signals in a desired manner may exist on an intelligent reflecting sur…
