Abstract

Этот способ перемежения битов выполняет перестановку битов для слов QC-LDPC-кода, состоящих из N циклических блоков из Q битов, и сегментирует упомянутые обработанные кодовые слова на несколько слов созвездия, состоящих из M битов. Кодовые слова сегментируются на FN/M секций свертки, и каждое слово созвездия ассоциируется с одной из FN/M секций свертки. Обработка перестановки битов выполняется таким образом, что слова созвездия состоят из F битов из каждого из M/F различных циклических блоков в ассоциированной секции свертки.
