Abstract
A system and method for cell synchronization suitable for a wireless signal including substantially identical synchronization signals that repeat in predetermined time intervals, the synchronization signals including a plurality of substantially identical symbols. For a plurality of candidate synchronization points: dividing the wireless signal into a plurality of signal segments, each equal or longer than the time interval, and each including a plurality of sub-segments having substantially same length as the symbol; performing symbol-length cross-correlations between an expected symbol and the sub-segments; performing segmented symbol-wise correlations between the cross-correlation results; calculating a cost function based on the results of the symbol-wise correlations; accumulating the cost functions across a plurality of signal segments; and selecting a coarse synchronization point from the plurality of candidate synchronization points based on the accumulated cost function; Estimating synchronization parameters e.g. time and frequency offset based on the selected synchronization point.
