- 論文の詳細を見る
The structure of bidirectional syndrome decoding for binary rate(n-1)/n convolutional codes is investigated. It is shown that for backward decoding based on the trellis of a syndrome former H^T, the syndrome sequence must be generated in time-reversed order using an extra syndrome former H^<*T> where H^* is a generator matrix of the reciprocal dual code of the original code. It is also shown that if the syndrome bits are generated once and only once using H^T and H^<*T>, then the corresponding two error sequences have the intersection of ν′× n error symbols, where ν′is the memory length of H^T.
