简介
Light Fidelity (Li-Fi) is a wireless visible light communication technique in which data is transmitted by light emmitting diodes (LEDs). However, this technology is still in the development stage and there are some problems that need to be overcome. One of these problems is disruptive effect of inter-symbol interference (ISI) at high speeds. Optical signals reaching a receiver from different paths cause ISI and increase in ISI decreases SNR. In this study, we presented an LED selection algorithm for indoor Li-Fi Systems in order to reduce ISI effect.
