Abstract
Synchronizing the clocks of nodes or stations in a communications network in a way that is independent of computation and switching time. This may be done by synchronizing pseudo-random noise clocks (found in the nodes of a spread spectrum communication system) or by synchronizing chip sequence clocks (found in the nodes of a CDMA communication system). In this way, the accuracy of synchronization should only be affected by the resolution of a matched filter (i.e., a facility to match or correlate bit sequences) in the node. Once synchronized, these nodes may be used to locate another node or station based on transmission propagation delays determined by the synchronization method.
