Abstract
A system and method in a digital TDMA telecommunication system for evaluating time slot offsets of asynchronously operating transmitters. The transmitters are equipped to receive a common reference clock signal, whereupon the value of the reference clock signal is recorded at transmission of specific time slots. The transmitters then perform a modulo operation on the recorded time and reports the result to a controlling node. Results of the modulo operation may then be compared with similar results reported by other transmission sources to the controlling node to determine relative time slot offsets between the transmission sources.
