Abstract
A method for calculating frequency offset using arc tangent calculations according to real part and imaginary part input values received externally. The method includes converting arc tangent equations for determining frequency offset into equations to perform log calculations; calculating frequency offset using linear approximation and the converted log equations; and dividing the real part input value to bit values of a predetermined size to realize a size similar to that of the imaginary part input value if a range of the frequency offset value to be calculated is small. With the use of the method, hardware area and power consumption may be reduced, and precise frequency offset may be calculated.
