Abstract

Many studies have focused on the implementation of VLC (Visible Light Communication) systems because it has several advantages compared to RF-based communications systems. However, most authors focus only on one-way communication. This article proposes an uplink communication system based on infrared light and software defined radio. For this purpose, we built analogue interfaces for transmission and reception, which are connected to an USRP (Universal Software Radio Peripheral). Finally, the bit error rate (BER) is measured using GNU Radio software. The obtained BER is 5.33 × 10-5 at a bit rate of 4 Mbps and 160 cm of distance between transmitter and receiver using QPSK modulation.
