1. A method of classifying a modulation type of a classification target signal by using a single sampling frequency in a receiving apparatus, the method comprising:
extracting I data having an in-phase component and Q data having a quadrature-phase component, sampled with a single sampling frequency, from the classification target signal received from a transmitting apparatus by using a preprocessor; and
analyzing features of the extracted I data and Q data to classify a modulation type of the classification target signal by using a classifier learned based on a machine learning method.
