    Abstract: In a Time Division Multiple Access (TDMA) cellular system, there is provided a mechanism for synchronization and equalization comprising: providing synchronization information (S/S) sufficiently removed from the start of a TDM slot so as to maintain the integrity of that synchronization information (S/S) at adjacent cells and providing that synchronization information (S/S) not so far removed from the start of the slot as to necessitate adaptive equalization of information preceding the synchronization information (S/S) for sufficiently reliable recovery. The equalization is further enhanced by providing, roughly midway between the synchronization information (S/S) and the end of the slot, additional information (CC) upon which equalization may retrain. Accordingly, equalizers perform retrospective, non-adaptive equalization of information preceding the synchronization information (S/S), perform adaptive equalization of information following that synchronization information (S/S), and retrain utilizing known bit-sequences elsewhere within the TDM slot; the additional information (CC) comprises known bit-sequences identifying cells.

The equalization is further enhanced by providing, roughly mid-way between the synchronization information (S/S) and the end of the slot, additional information (CC) upon which equalization may retrain. Accordingly, equalizers perform retrospective, non-adaptive equalization of information preceding the synchronization information (S/S), perform adaptive equalization of information following that synchronization information (S/S), and retrain utilizing known bit-sequences elsewhere within the TDM slot; the additional information (CC) comprises known bit-sequences identifying cells.
