Abstract:
A method and an apparatus for detecting an envelope using a difference between sampling signals are provided. The method includes generating sampling sets based on sampling signals of a modulated signal, and determining a sampling set from the sampling sets. The method further includes determining an envelope component value associated with a sampling signal among sampling signals included in the determined sampling set, based on a difference between the sampling signals included in the determined sampling set, and a difference between sampling signals included in each of the sampling sets other than the determined sampling set. The method further includes detecting an envelope of the modulated signal based on the envelope component value.
