Illuminating Networks: Enhancing Visible Light Communication with Physical-Layer Network Coding (PNC-VLC Scheme)

Abdellah Tahenni, Fatiha Merazka

TL;DR

An integrated PNC-VLC framework including physical-layer signal processing algorithms and medium access control approaches is developed including physical-layer signal processing algorithms and medium access control approaches for enhancing throughput by boosting data transmission at relay nodes.

Abstract

Wireless communications using light waves are called visible light communication. A technique called Physical-layer Network coding allows several users to communicate simultaneously over the same channel in a distributed space-time Coding scheme. Herein, we report a new PNC-VLC one-to-many scheme using physical-layer network coding in VLC system for enhancing throughput by boosting data transmission at relay nodes. We develop an integrated PNC-VLC framework including physical-layer signal processing algorithms and medium access control approaches. Our proposed technique is then modelled mathematically and compared with some of the VLC and PNC-VLC schemes under various channel conditions and scenarios. Our investigation revealed that our proposed technique performed better than traditional PNC schemes in achieving better Bit Error Rate performance in different channel
