Аннотация
Для повышения эффективности передачи информации в КВ-диапазоне исследована задача определения занятости радиоканалов с полосами 3…24 кГц. Разработаны алгоритмы и методики оценки занятости радиоканалов при обработке экспериментальных уровней шума в КВ-диапазоне. На базе технологии SDR разработан лабораторный образец программно-аппаратного комплекса мониторинга спектра помех. Получены результаты анализа влияния геофизических факторов на загруженность КВ-радиоканалов с различной полосой частот.
Ключевые слова: занятость спектра; широкополосный сигнал; уровень шума; минутная доступность радиоканала; адаптивный порог.
