ABSTRACT:
An apparatus and a method for measuring a moving distance in a mobile communication terminal. A Doppler frequency over a time interval for measuring a moving speed of the Doppler frequency is measured or calculated. The moving speed is calculated. The moving distance is calculated using the moving speed and the time interval.
