Wideband Physical Layer Security in Mixed Near-Field and Far-Field Communications
Yunpu Zhang, Changsheng You, Hing Cheung So
Prior studies on wideband physical layer security (PLS) have mostly focused on either far-field or near-field communication systems. In this paper, we investigate PLS in a more gen…
Near-Field Beam Training: Joint Angle and Range Estimation with DFT Codebook
Xun Wu, Changsheng You, Jiapeng Li +1
Prior works on near-field beam training have mostly assumed dedicated polar-domain codebook and on-grid range estimation, which, however, may suffer long training overhead and degr…
Fast Near-Field Beam Training for Extremely Large-Scale Array
Yunpu Zhang, Xun Wu, Changsheng You
In this letter, we study efficient near-field beam training design for the extremely large-scale array (XL-array) communication systems. Compared with the conventional far-field be…
Multi-Active Multi-Passive (MAMP)-IRS Aided Wireless Communication: A Multi-Hop Beam Routing Design
Yunpu Zhang, Changsheng You, Beixiong Zheng
Prior studies on intelligent reflecting surface (IRS) have mostly considered wireless communication systems aided by a single passive IRS, which, however, has limited control over…
Multi-Hop Beam Routing for Hybrid Active/Passive IRS Aided Wireless Communications
Yunpu Zhang, Changsheng You
Prior studies on intelligent reflecting surface (IRS) have mostly considered wireless communication systems aided by a single passive IRS, which, however, has limited control over…
