Pilot-Free Unsourced Random Access Via Dictionary Learning and Error-Correcting Codes
Zhentian Zhang, Jian Dang, Zaichen Zhang +3
Massive machine-type communications (mMTC) or massive access is a critical scenario in the fifth generation (5G) and the future cellular network. With the surging density of device…
Fast and Arbitrary Beam Pattern Design for RIS-Assisted Terahertz Wireless Communication
Jian Dang, Zaichen Zhang, Yewei Li +3
Reconfigurable intelligent surface (RIS) can assist terahertz wireless communication to restore the fragile line-of-sight links and facilitate beam steering. Arbitrary reflection b…
A New High Energy Efficiency Scheme Based on Two-Dimension Resource Blocks in Wireless Communication Systems
Kang Liu, Zaichen Zhang, Jian Dang +4
Energy efficiency (EE) plays a key role in future wireless communication network and it is easily to achieve high EE performance in low SNR regime. In this paper, a new high EE sch…
Outage Analysis and Beamwidth Optimization for Positioning-Assisted Beamforming
Bingcheng Zhu, Zaichen Zhang, Julian Cheng
Conventional beamforming is based on channel estimation, which can be computationally intensive and inaccurate when the antenna array is large. In this work, we study the outage pr…
Performance of Wireless Optical Communication With Reconfigurable Intelligent Surfaces and Random Obstacles
Haibo Wang, Zaichen Zhang, Bingcheng Zhu +5
It is difficult for free space optical communication to be applied in mobile communication due to the obstruction of obstacles in the environment, which is expected to be solved by…
