Совместное применение неоднородной модуляции и Ð¿Ð¾Ð¼ÐµÑ Ð¾ÑƒÑÑ‚Ð¾Ð¹Ñ‡Ð¸Ð²Ð¾Ð³Ð¾ кодирования

Abstract

В работе осуществляется поиск сочетания параметров неоднородной модуляции и помехоустойчивого кода, при котором достигается наибольший выигрыш по сравнению со схемой с однородной модуляцией и помехоустойчивым кодированием с такой же кодовой скоростью. Рассмотрены два помехоустойчивых кода: турбо код и LDPC код. Результаты моделирования в среде MatLab показали, что для модели с турбокодированием энергетический выигрыш составил 0.2 дБ по сравнению с моделью с однородной модуляцией (турбо-код, модуляция QAM16). Для модели с LDPC кодированием энергетический выигрыш составил 0.3 дБ по сравнению с моделью с однородной модуляцией (LDPC-код, модуляция QAM16).
