# An SDR Implementation of a Visible Light Communication System Based on the IEEE 802.15.7 Standard

## TL;DR

This paper presents a low-cost SDR-based implementation of a real-time visible light communication system adhering to IEEE 802.15.7, validated through laboratory over-the-air tests.

## Contribution

It introduces a practical, open-source SDR testbed for visible light communication based on IEEE 802.15.7 using commercial hardware and software frameworks.

## Key findings

- Successful real-time over-the-air communication demonstration
- Cost-effective implementation with commercial off-the-shelf components
- Validation of system performance in laboratory environment

## Abstract

The aim of this paper is to present an implementation of a functional IEEE 802.15.7 real-time testbed based on the Software Defined Radio (SDR) concept. This implementation is built with low cost commercial off-the-shelf (COTS) analog devices and the use of Universal Software Radio Peripheral version 2 (USRP2) equipment combined with a generic object-oriented framework that takes advantage of several open source software libraries. The prototype is validated in a controlled laboratory environment with an over-the-air measurement campaign.
