Abstract

Dans l'un de ses aspects, cette invention concerne un procédé servant à synchroniser des terminaux radio dans un système de radiocommunication. A cet effet, un terminal radio maître (M1) transmet des premiers signaux de synchronisation (pilote), lesquels sont reçus par au moins un premier et un second terminal radio (T1, T2) et sont utilisés pour synchroniser ces premier et second terminaux radio (T1, T2) sur le terminal radio maître (M1), le premier terminal radio (T1) transmet ensuite des signaux de données (données) et des second signaux de synchronisation (préambule) au second terminal radio (T2), lequel peut ainsi se synchroniser sur le premier terminal radio (T1) et détecter les signaux de données (données) reçus.
