| Abstract: | A
node synchronisation technique for rate (v-1)/v convolutional codes is
presented which can resolve a loss of node synchronisation with only a
single trial. The algorithm, which is implemented external to the
decoder, is based on extracting evidence in support of the in-sync or
off-sync hypotheses from the syndrome and other sequences associated
with the convolutionally encoded received channel symbols. Simulation
results are presented for rate R=(v-1)/v punctured codes derived from
the well known standard NASA, constraint length 7, rate 1/2 code.
