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…
Performance Analysis of Hybrid RF-Reconfigurable Intelligent Surfaces Assisted FSO Communication
Haibo Wang, Zaichen Zhang, Bingcheng Zhu +1
Optical reconfigurable intelligent surface (ORIS) is an emerging technology that can achieve reconfigurable optical propagation environments by precisely adjusting signal's reflect…
A Novel Method to Estimate the Coordinates of LEDs in Wireless Optical Positioning Systems
Kehan Zhang, Zaichen Zhang, Bingcheng Zhu
Traditional visible light positioning (VLP) systems estimate receivers' coordinates based on the known light-emitting diode (LED) coordinates. However, the LED coordinates are not…
Tracking System for Optical Mobile Communication and the Design Rules
Kehan Zhang, Bingcheng Zhu, Zaichen Zhang +1
Free space optical communication has been applied in many scenarios because of its security, low cost and high rates. In such scenarios, a tracking system is necessary to ensure an…
Sparse Channel Estimation and Hybrid Precoding Using Deep Learning for Millimeter Wave Massive MIMO
Wenyan Ma, Chenhao Qi, Zaichen Zhang +1
Channel estimation and hybrid precoding are considered for multi-user millimeter wave massive multi-input multi-output system. A deep learning compressed sensing (DLCS) channel est…
Molecular Polar Belief Propagation Decoder and Successive Cancellation Decoder
Zhiwei Zhong, Lulu Ge, Zaichen Zhang +2
By constructing chemical reaction networks (CRNs), this paper proposes a method of synthesizing polar decoder using belief propagation (BP) algorithm and successive cancellation (S…
