Аннотация:

Передача данных при мобильной беспроводной связи, как правило, использует радиочастотный диапазон. Однако перегруженность его спектра не может удовлетворить растущие требованияперспективных приложений с высокой скоростью передачи данных. В последнее время развитие оптической беспроводной связи (optical wireless communication (OWC)) сделало передачу в широком оптическом спектре рентабельной и практичной альтернативой перегруженным радиочастотным беспроводным технологиям. Наряду с повсеместным использованием в бытовой электронике (планшеты и смартфоны), развиваются методы, основанные на оптических камерах связи (ОКС) (OCC — optical camera communication) и датчиках изображений (image sensor, IS), перспективных для использования в таких областях, как интеллектуальный транспорт, автомобильная связь, технологии захвата движения, локализация расположения объектов как внутри, так и вне помещений, а также доступ в Интернет Вещей. Недавние разработки в области связи, комбинирующие камеры или датчики изображения с интеллектуальными устройствами с низкой сложностью реализации, делают оптические камеры связи очень привлекательными как дополнительных устройств в каналах высокоскоростных линий оптической связи.
Представлен всесторонний обзор оптических камер связи, принципов их работы и недавних мероприятий по стандартизации. Этот обзор охватывает несколько аспектов оптических камер связи, таких как приёмопередатчики, многоканальные системы (multiple-input multiple-output, MIMO) и диверсификацию. В нём описаны различные применения OКC. В нём также рассматриваются некоторые практические ограничения, схемы модуляции и методы кодирования с исправлением ошибок для систем OКC. Наконец, в последнем разделе этого обзора представлен анализ проблем и направлений будущих исследований.

Ключевые слова:

оптическая беспроводная связь, оптическая камера связи, радиочастота, связь в видимом свете (VLC), датчик изображения, камера

Коды OCIS: 040.0040; 040.1490; 230.0230; 060.4510
