Design of an Optimized Visible Light Communication Link Systems using Matlab for hospital Communication

Abstract

Visible Light Communication (VLC) is an emerging wireless technology that uses light-emitting diodes (LEDs) for high-speed data transmission and offers a reliable alternative to traditional Radio Frequency (RF) communication, especially in hospital environments where RF signals may cause electromagnetic interference with sensitive medical equipment. In this paper, an optimized VLC-based communication system for hospital applications is proposed and implemented using MATLAB to ensure safe and efficient transmission of patient data such as heart rate and oxygen levels. The system performance is analyzed using key parameters like Signal-to-Noise Ratio (SNR) and Bit Error Rate (BER), and further improved using optimization techniques and Artificial Neural Networks (ANN) under varying conditions such as distance and ambient light noise. The results demonstrate that the proposed VLC system provides secure, interference-free, and energy-efficient communication, making it highly suitable for modern healthcare environments.
