Method and device for decoding duobinary signals transmitted in bursts.

摘要

In order to decode data transmitted in the form of duobinary encoded signals transmitted in bursts in a multiplex, the multiplex is baseband digitised and subjected to a Viterbi decoding by masking those parts of the multiplex which would cause the duobinary encoding rule to be violated due to interruptions between bursts. The method can be used in particular to optimise the Viterbi decoding of sound signals and of data from a D-MAC or D2-MAC/PACKET multiplex. <IMAGE>
