Virtual Polarization Modulation: Enabling CSI-Free DCO-OFDM over Dynamic OWC Channels
Tian Cao, Ping Wang, Tianfeng Wu +2
In dynamically varying optical wireless communication (OWC) links, conventional quadrature amplitude modulation (QAM) in optical orthogonal frequency-division multiplexing (OFDM) r…
Path Loss Modeling for NLoS Ultraviolet Channels Incorporating Scattering and Reflection Effects
Tianfeng Wu, Fang Yang, Fei Li +6
This paper tackles limitations in existing non-line-of-sight (NLoS) ultraviolet (UV) channel models, where conventional approaches assume obstacle-free propagation or uniform radia…
Channel Modeling for Ultraviolet Non-Line-of-Sight Communications Incorporating an Obstacle
Tianfeng Wu, Fang Yang, Tian Cao +5
Existing studies on ultraviolet (UV) non-line-of-sight (NLoS) channel modeling primarily focus on scenarios without any obstacle, which makes them unsuitable for small transceiver…
Modeling of UV NLoS Communication Channels: From Atmospheric Scattering and Obstacle Reflection Perspectives
Tianfeng Wu, Fang Yang, Tian Cao +5
As transceiver elevation angles increase from small to large, existing ultraviolet (UV) non-line-of-sight (NLoS) models encounter two challenges: i) cannot estimate the channel cha…
