Channel characterization in screen-to-camera based optical camera communication
Vaigai Nayaki Yokar, Hoa Le Minh, Zabih Ghassemlooy +1
With the increase in optical camera communication (OCC), a screen to camera-based communication can be established. This opens a new field of visible light communication (VLC) know…
A Novel Frame Identification and Synchronization Technique for Smartphone Visible Light Communication Systems Based on Convolutional Neural Networks
Vaigai Nayaki Yokar, Hoa Le-Minh, Xicong Li +5
This paper proposes a novel, robust, and lightweight supervised Convolutional Neural Network (CNN)-based technique for frame identification and synchronization, designed to enhance…
An Image Processing Based Blur Reduction Technique in Smartphone-to-Smartphone Visible Light Communication System
Vaigai Nayaki Yokar, Hoa Le-Minh, Zabih Ghassemlooy +1
In this paper, we present a blur reduction technique for smartphone-to-smartphone visible light communications (S2SVLC). The key technique it to avoid the repeated scanning of the…
Fast Link Recovery via PTP-synchronized Nanosecond Optical Switching
V. Yokar, A. Mehrpooya, Y. Teng +5
This paper proposes and validates a PTP-synchronized 8.4ns optical switching with a 100ns jitter at the switching edges. This approach is adopted and demonstrated for instant netwo…
