Evaluating Li-Fi System Performance in the Presence of External While Light Interference

The development in optical communications has made the possibility of communication by lighting rooms possible through Li-Fi technology, which is a technology for transmitting data via light. Maintaining the performance of the network is one of its most important components in the shadow of external light, whether sunlight, industrial light, or any other light source, and this effects the efficiency of the system, data rate, and BER. In this research, the effect of a white light will be discussed on the Li-Fi system, using multiple modulation patterns and getting the good performance of  the system design in Optisystem  and Matlab for three types of modulation and power distribution.
