Abstract
A CDMA mobile communication system is operated asynchronously while using common forward channel PN and Walsh codes. Such operation is enabled by devices in the system that provide measurements of the instantaneous offsets between PN codes of neighboring base stations. Knowledge of instantaneous offsets may be maintained and used to identify base station signals to enable handovers to neighboring base stations. Instantaneous offsets may also be processed over time to identify states of imminent collision so that corrective action can be taken to avoid or minimize collision effects.
