Abstract: A device and a method for estimating an offset frequency of a portable terminal are provided to easily detect and remove an error generation symbol by using a decision region, and to interpolate a phase value of an adjacent symbol by averaging the phase value, thereby minimizing a least square error. A de-rotation unit(100) processes a symbol signal into a training sequence symbol signal, and offsets a phase difference between QPSK modulation signals. A phase calculator(110) inputs the offset signals, and detects a phase value. A phase unwrapper(120) compensates for an error caused during a function calculation of the detected phase value. An error detector(130) analyzes a signal inputted from the unwrapper(120), and removes a symbol signal detected in other region except a decision region. An interpolator(140) obtains an average value of symbol signals adjacent to the removed symbol signal. An offset estimator(150) operates an offset frequency estimation value having the smallest least square error.
