The present invention relates to differential, locally updating Viterbi decoder characterized in that it contains connection management block (802, 810, 812) which enables decoding a bit per cycle by trellis diagram uniting (810) and distributing procedure (812). Furthermore, the invention is also characterized in that it contains a path metric update block, in which the monotonical growth of state metrics is avoided by a bounding procedure in a path metric update (808).
