Abstract

Раскрыто устройство кодирования потока информационных битов двоичного исходного сигнала (S) в поток информационных битов двоичного сигнала (C) канала передачи, в котором поток битов исходного сигнала разделен на n-разрядные исходные слова (x, x), а устройство содержит в себе средство (ЛС) преобразования, выполненное с возможностью осуществления преобразования указанных исходных слов в соответствующие m-разрядные слова (y, y, y) канала передачи. Каждое n-разрядное исходное слово вместе с другим n-разрядным исходным словом образуют собой пару исходных слов. Значения n-разрядных исходных слов отличаются между собой только значением бита в q-том разряде, причем величина q является постоянной. Пары исходных слов разделены на первую часть пар и остальную часть пар. Средство (ЛС) преобразования дополнительно осуществляет преобразование n-разрядных исходных слов, принадлежащих к первой части пар, в соответствующие m-разрядные слова канала передачи таким образом, что преобразование каждого из указанных n-разрядных исходных слов выполняют с сохранением четности, а преобразование n-разрядных исходных слов, принадлежащих к остальной части пар, в соответствующие m-разрядные слова канала передачи оно осуществляет таким образом, что преобразование для каждого из указанных n-разрядных исходных слов выполняют с инверсией четности (см. табл. I) (фиг. 1). Кроме того, раскрыто устройство декодирования, осуществляющее декодирование сигнала канала передачи, полученного посредством устройства кодирования.Международная заявка была опубликована вместе с отчетом о международном поиске.
