Abstract: A method of synchronizing a base station and a remote station is presented. The base station is communicatively coupled with the remote station and a reference network. The base station clock signal is compared with a reference clock signal derived from the reference network and adjusted accordingly. The adjusted base station clock signal is then used to generate timing information in the form of a preamble, which is periodically transmitted from the base station over a wireless communication network to the remote station where a clock signal is generated. The remote station compares the clock signal with the timing information and adjusts the clock signal accordingly. This is done without reference to an external clock.

Abstract: As part of a preferred communication protocol, base stations which are synchronized to a PSTN of a wireless communication network, periodically transmits a preamble. A remote detects the preamble and, upon verification of the data contained in the base station transmission, sets its counter to an initialized state based on the received preamble. An early/late analysis of each subsequently received base station timing pulse is used to adjust both the mobile station timing and to adjust the output frequency of the mobile station master clock and codec clock to effectively maintain end to end synchronization with the respective base station and the PSTN throughout the duration of an established communication link.
