Abstract

The structure of bidirectional syndrome decoding for binary rate (n-1)/n convolutional codes is investigated. It is shown that for backwarddecoding 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 v(1) x n error symbols, where v(1) is the memory length of H-T.
