Abstract

Устройство обработки данных отображает входные символы, предназначенные для передачи, в заданное количество сигналов поднесущей ортогонального мультиплексированного с частотным разделением (ОМЧР) символа. Процессор обработки данных включает в себя запоминающее устройство перемежителя, который считывает заданное количество символов данных для отображения на сигналы поднесущей ОМЧР. Запоминающее устройство перемежителя считывает символы данных на поднесущие ОМЧР для выполнения отображения, причем считывание с запоминающего устройства выполняют в ином порядке, чем занесение в запоминающее устройство, порядок определяют по набору адресов, в результате чего символы данных перемежают на сигналы поднесущей. Набор адресов генерируют с генератора адреса, содержащего линейный регистр сдвига с обратно
