Multiuser Diversity Over Parallel and Hybrid FSO/RF Links and Its Performance Analysis

IEEE Photonics Journal, 2016
Hybrid free-space optical (FSO)/radio-frequency (RF) communication has emerged as an effective solution for high-data-rate wireless transmission. In this paper, multiuser diversity over parallel and hybrid FSO/RF links is discussed.

Measuring the Gap Between the Maximum Predictability and Prediction Accuracy of Human Mobility

IEEE Access, 2020
It has been claimed that human mobility is highly predictable and an upper bound of 93% predictability is achievable. However, there is a significant gap between the upper bound of predictability and the actual prediction accuracy in many data sets. This

LED Half-Power Angle Optimization for Ultra-Dense Indoor Visible Light Communication Network Deployment

IEEE Open Journal of the Communications Society, 2020
Due to limited interference range, the advantage of visible light communication (VLC) over wireless fidelity (WiFi) lies more in the unit-area transmission rate rather than the single-link transmission rate.

Integrated transceivers for optical wireless communications

IEEE Journal of Selected Topics in Quantum Electronics, 2005
Line-of-sight free-space optical links can provide extremely high bandwidth communications, but this usually requires that transmitter and receiver are precisely aligned. In order to allow terminals to be mobile, links must be able to track users within their field of view so that the link is maintained.
