# Infrared uplink design for visible light communication (VLC) systems with beam steering

## TL;DR

This paper proposes an infrared uplink VLC system with beam steering and a 4-branch ADR to achieve high data rates, demonstrating up to 3.57 Gb/s with simple modulation.

## Contribution

It introduces a novel infrared uplink design with beam steering and an angle diversity receiver for high data rate VLC systems.

## Key findings

- Achieved data rates up to 3.57 Gb/s using OOK.
- Analyzed delay spread and SNR with the proposed system.
- Demonstrated the effectiveness of beam steering in uplink VLC.

## Abstract

Providing uplink high data rate is one of the big concerns in visible light communication (VLC) systems. This paper introduces an uplink VLC system based on an infrared transmitter with beam steering to provide high data rates. In this work, a 4 branches angle diversity receiver (ADR) is used and the resultant delay spread and SNR are examined. The proposed system achieved data rates up to 3.57 Gb/s using simple on-off-keying (OOK).
