Mobile communication terminal and method of clibrating frequency in the same
First Claim
1. A mobile communication terminal including:
- (a) a first unit for calibrating a frequency;
(b) a global positioning system (GPS) module; and
(c) a processor which electrically connects said first unit and said global positioning system module to each other, wherein said first unit counts the number of an intermediate frequency (IF) signal generated by converting a frequency of a signal transmitted from a base station, said processor coverts a count of said intermediate signal obtained while said first unit is in lock-up condition, into a real count offset, and said global positioning system module counts the number of a signal transmitted from a circuit which generates an operational frequency of said mobile communication terminal, and calibrates said number of said signal with said real count offset.

Abstract
A mobile communication terminal includes (a) a first unit for calibrating a frequency, (b) a global positioning system (GPS) module, and (c) a processor which electrically connects the first unit and the global positioning system module to each other. The first unit counts the number of an intermediate frequency (IF) signal generated by converting a frequency of a signal transmitted from a base station, the processor coverts a count of the intermediate signal obtained while the first unit is in lock-up condition, into a real count offset, and the global positioning system module counts the number of a signal transmitted from a circuit which generates an operational frequency of the mobile communication terminal, and calibrates the number of the signal with the real count offset.
