Abstract: A frequency error estimator using the second order loop filter in a mobile communication system and an operating method thereof are provided to supply high estimation accuracy without damaging tracing about time variation of a frequency. A correlator(10) produces a correlation value through a received signal and a reference code. An FED(Ferquency Error Detector)(20) produces a cross-product error through the correlation value. The FED detects a frequency error through the correlation value about a previous sample from the correlator. The frequency error is filtered so that a loop filter improves an S/N(Signal to Noise) ratio.
