Abstract
A method and an apparatus are provided for setting a cut-off frequency of an analog filter of a reception device for wireless communication. A deviation value is obtained that corresponds to an error between a first gain value based on an ideal transfer function curve and a second gain value based on a measured transfer function curve at an arbitrary frequency of a frequency band in which a constant interval is maintained between a slope of the ideal transfer function curve and a slope of the measured transfer function curve. A cut-off frequency that is used to measure the measured transfer function curve in a real environment, is corrected based on the obtained deviation value.
