Vorrichtung und Verfahren zur automatischen Frequenzregelung in einem mobilen Kommunikationsendgerät

摘要

The terminal has a complex correlator detecting a pilot signal from a base station. An automatic frequency controller (AFC) detects a current peak position value from the pilot signal and calculates an AFC voltage based on a difference value between the current peak position value and a previous peak position value. An oscillator (140) generates an oscillation frequency for controlling a demodulator based on the AFC voltage. An independent claim is also included for an automatic frequency controlling method of a mobile communication terminal.
