# Real-Time Experimental Demonstration of Multi-band CAP Modulation in a VLC System with Off-the-Shelf LEDs

## TL;DR

This paper presents the first real-time experimental demonstration of multi-band CAP modulation in visible light communication using standard LEDs, achieving high data rates suitable for HD streaming.

## Contribution

It introduces a real-time VLC system employing off-the-shelf LEDs with m-CAP modulation, validated through FPGA-based USRPs, demonstrating practical high-speed optical communication.

## Key findings

- Achieved data rates up to ~30 Mb/s.
- First real-time demonstration of m-CAP in VLC with off-the-shelf LEDs.
- Supports high-definition television streaming.

## Abstract

We demonstrate, for the first time, m-CAP modulation using off-the-shelf LEDs in a VLC in real time experimental setup using field programmable gate arrays based in universal software radio peripherals (USRPs). We demonstrate transmission speeds up to ~30 Mb/s can be achieved, which supports high definition television streaming.
