Sparse Channel Estimation for SIM-based mmWave Near-Field Communications
Jiancheng An, Enyu Shi, Jiayi Zhang +4
In this paper, we address the channel estimation (CE) problem in SIM-based multi-user (MU) millimeter-wave (mmWave) near-field communication systems. To address the severe path los…
Tag-based Physical-Layer Authentication Against Message Interference
Lei Yao, Boxiang He, Shilian Wang +2
Tag-based Physical-Layer Authentication (PLA) has attracted significant attention in recent years due to its low complexity, high security, and low latency. Traditional tag-based P…
