ABSTRACT:
A path-select-signal memory section in the Viterbi detector outputs each decoded data B′Sikcorresponding to a branch that occurred a prescribed time ago in a surviving path to each state at a present time, in response to path select signals SEL0, SEL1. A shift register stores the path select signals SEL0, SEL1in order of time. A binary output unit outputs a decoded bit corresponding to a branch that occurred a prescribed time ago in a surviving path. Output signal lines of the binary output unit and a selector train are connected according to a trellis diagram that corresponds to encoding operation.
