<p>A frequency recovery apparatus and a mobile broadcast reception system utilizing the frequency recovery apparatus are disclosed. The frequency recovery apparatus estimates a fractional frequency offset value using I and Q components of a correlation value of a guard interval and compensates for the estimated fractional frequency offset value, such that the problem of ambiguity which may occur in a specific position corresponding to 0.5 times a subcarrier spacing is solved, and the fractional frequency offset can be stably estimated and compensated for.
