Handover-Aware Trajectory Optimization for Cellular-Connected UAV
Xiangming Du, Shuowen Zhang, Francis C. -M. Lau
In this letter, we study a cellular-connected unmanned aerial vehicle (UAV) which aims to complete a mission of flying between two pre-determined locations while maintaining satisf…
Trilateration-Based Device-Free Sensing: Two Base Stations and One Passive IRS Are Sufficient
Qipeng Wang, Liang Liu, Shuowen Zhang +1
The classic trilateration technique can localize each target based on its distances to three anchors with known coordinates. Usually, this technique requires all the anchors and ta…
Exploiting Temporal Side Information in Massive IoT Connectivity
Qipeng Wang, Liang Liu, Shuowen Zhang +1
This paper considers the joint device activity detection and channel estimation problem in a massive Internet of Things (IoT) connectivity system, where a large number of IoT devic…
A New Channel Estimation Strategy in Intelligent Reflecting Surface Assisted Networks
Rui Wang, Liang Liu, Shuowen Zhang +1
Channel estimation is the main hurdle to reaping the benefits promised by the intelligent reflecting surface (IRS), due to its absence of ability to transmit/receive pilot signals…
Double-IRS Aided MIMO Communication under LoS Channels: Capacity Maximization and Scaling
Yitao Han, Shuowen Zhang, Lingjie Duan +1
Intelligent reflecting surface (IRS) is a promising technology to extend the wireless signal coverage and support the high performance communication. By intelligently adjusting the…
On Massive IoT Connectivity with Temporally-Correlated User Activity
Qipeng Wang, Liang Liu, Shuowen Zhang +1
This paper considers joint device activity detection and channel estimation in Internet of Things (IoT) networks, where a large number of IoT devices exist but merely a random subs…
