Аннотация

Короткий обзор посвящен такой развивающейся технологии, как связь по видимому диапазону длин волн. С ростом количества передаваемой информации между пользователями связь по видимому свету становится все более актуальной опцией организации каналов передачи информации благодаря отсутствию необходимости лицензировать частотный диапазон вещания, высокой емкостью канала связи, высокой помехоустойчивости, высокой защищенности канала связи. В работе представлены различные системы передачи данных на основе белых люминофорных светодиодов и RGB светодиодов, которые используют различные схемы модуляции и обработки сигнала для повышения скорости передачи информации.

Ключевые слова

связь в видимом диапазоне длин волн (VLC); оптическая беспроводная связь (OWC); free space optics (FSO); OFDM, QAM модуляция; Li-Fi
