Демодулятор SEFDM-сигналов на основе M-BCJR алгоритма

Abstract

Ð’ работе предложен метод снижения вычислительной сложности MAX-log-MAP (BCJR) демодулятора SEFDM-сигналов путем применения неполной решетки, в которой на каждом шаге используется только M узлов (M-BCJR). Выполнен анализ вычислительной сложности полученного алгоритма, приведена формула для коэффициента сокращения вычислительной сложности по сравнению с Ð¸ÑÑ Ð¾Ð´Ð½Ñ‹Ð¼ алгоритмом. Ð’ среде Matlab выполнено имитационное моделирование для оценки Ð¿Ð¾Ð¼ÐµÑ Ð¾ÑƒÑÑ‚Ð¾Ð¹Ñ‡Ð¸Ð²Ð¾ÑÑ‚Ð¸ приема SEFDM-сигналов с использованием предложенного алгоритма.
