Abstract
The present invention pertains to a self-synchronization apparatus and method for use in a multiple access channel communication network. In an embodiment of the present invention, the communication system is a wireless mobile telephone network having a service area including one or more base stations and multiple mobile stations. The base and mobile stations are in communication with a Global Positioning System (GPS). A mobile station communicates with a particular base station through a TDMA radio communication link. Each mobile station is assigned one time slot for transmitting data to the base station and a second time slot for receiving data from the base station. The mobile station and the base station exchange their respective GPS positions. A transmitting station determines a time delay based on the receiving station's GPS position. This time delay is used to advance a transmission to the receiving station so that it is received at the receiving station at a time that coincides with the start of the time slot.
