<P>PROBLEM TO BE SOLVED: To provide a method for generating a timing signal for operating a wireless terminal, in a wireless system having a wireless system time base. <P>SOLUTION: The method includes a step of generating a calibrated slow clock, a step of generating absolute time values, by counting the calibrated slow clock to provide a unified time base, a step of timing events in the wireless system, based on the absolute time values of the unified time base independently of the wireless system time base. The method of generating the calibrated clock includes a step of receiving a free-running fast clock, a step of receiving a free-running slow clock, a step of modifying the free-running slow clock, to provide a calibrated slow clock, having a specified frequency relation to the fast clock, and a step of providing a phase-compensation signal which represents phase error in the calibrated slow clock. <P>COPYRIGHT: (C)2007,JPO&INPIT |
