Abstract
A system processes communication signals in a network [100, 200]. The system may obtain time of arrival information for chunks of data in the network and construct a signal [410, 420] to represent the time of arrival information. The signal may consist of data that is non-uniformly spaced. The system may process the signal using a Lomb technique to obtain periodicity information [600, 800] about the signal.
