Improving the Performance of SINR for Indoor VLC System

Visible Light Communication (VLC) is an emerging technology that utilizes LED lighting to transmit data through modulated light intensity. The concept of VLC is based on simple principles. LED bulbs are modulated at high frequencies that are invisible to the human eye. Fluctuations in light intensity are detected by photodetectors, such as photodiodes, which then decode the transmitted data. This paper aims to reduce the interference that occurs at the user terminals. Data services are allocated to users according to channel conditions. To achieve a better performance rate by reducing interference and improving SINR performance, the proposed approach is using the Successive Interference Cancellation (SIC) technique. Comparative simulations are performed for the conventional approach and the proposed approach. The improved performance of the system is noted in the proposed approach. The main aim of this paper is to improve system performance and reduce complexity by limiting interference among users. This increases the efficiency of the system.
