Soft-decision syndrome based node synchronisation
Janak Sodha, D.J. Tait · Electronics Letters · 1990
A node synchronisation technique based on extracting the syndrome sequence, associated with convolutionally encoded received channel symbols, is extended to incorporate soft-decision information. The extension involves defining a measure of confidence per syndrome bit producing a ‘soft’ syndrome. The potential benefits of the new algorithm are investigated. It is shown that improvements are possible but only at the expense of storage requirements.
