Abstract
A device for initializing a Viterbi decoder in a receiver for signals transmitted in the form of bursts, each burst comprising a synchronization word and message data that has undergone convolutional coding in a transmitter, the position of the message data relative to the synchronization word being known, includes a detector for detecting the synchronization word, a multiplexer for applying the received signals to the Viterbi decoder in the presence of the message data and for applying to the Viterbi decoder, immediately before and immediately after the message data, a code sequence generated locally, free of errors and having a length at least equal to the truncation length of the Viterbi decoder.
