Abstract
A method for estimating a frequency offset of a reception signal and, more particularly, a signal processing method which can be applied to a receiver modem in a wireless communication system, are provided. The method includes using an absolute value within a specific time area in an inverse discrete fourier transform (IDFT) output of a decorrelation signal between a reception signal and a reference signal, and enabling a highly approximate estimation of a frequency offset through only a single decorrelation test using a characteristic of a predetermined permutation of a signal.
