Definitions
- a GSM subscriber unit can estimate the time of arrival of signals transmitted from various base stations by cross-correlating the received signal by the local replica of the signal to be detected.
- the training sequence of the GSM bursts can be used for that purpose, whether it is a normal burst, dummy burst or synchronisation burst (SCH) as this information is known for all bursts.
