    • PURPOSE: An apparatus and a method for compensating a frequency offset in a mobile communication system are provided to reduce the length of a preamble by compensating a frequency offset by a train sequence received after being inserted in data symbols. CONSTITUTION: An adder(712) adds a phase channel signal and an orthogonal phase channel signal outputted by down-converting train symbols and outputs an added channel signal consisting of only a cosine wave component or a sine wave component. A subtractor(714) subtracts an in-phase channel signal and an orthogonal phase channel signal outputted by down-converting the train sequences and outputs a subtracted channel signal consisting of only a sine wave component or a cosine wave component corresponding to the added channel signal. A frequency offset estimator(716) receives the first and second added channel signals and the first and second subtracted channel signals that are provided at two different points, obtains the first phase value by the first added channel signal and the first subtracted channel signal and the second phase value by the second added channel signal and the second subtracted channel signal, and estimates a frequency offset by a tilt of the secondary straight line formed by the first and second phase values. A frequency offset compensator(614) compensates a frequency by a frequency offset value which is supplied from the frequency offset estimator(716).
