Abstract
The techniques described herein relate to methods, apparatus, and computer readable media configured to decode modulated data. A modulated signal is received. A format of the modulated signal is determined, wherein the format can include a first format comprising a first type of modulated signal, or a second format comprising the first type of modulated signal and a second type of modulated signal that is different than the first type. The modulated signal is decoded by determining a frequency shift amount based on the format of the modulated signal, shifting a frequency band of the first type of modulated signal from an original position to a shifted position, thereby shifting a center frequency of the first type of modulated signal by the frequency shift amount, and filtering, based on the format of the modulated signal, signals outside of the frequency band of the shifted first type of modulated signal.
