Abstract
A method of receiving information is provided. The method, performed at a system for information transfer, includes receiving a first signal pulse and determining a first frequency band associated with the first signal pulse. The method includes, in accordance with a determination that the first frequency band is a respective frequency band in a first set of frequency bands, determining, from a predefined set of symbols associated with the first set of frequency bands, a first symbol associated with the first frequency band and represented by the first signal pulse. The first set of frequency bands includes a second frequency band that is a nearest frequency band in the first set of frequency bands to the first frequency band. The first frequency band has a first center frequency; the second frequency band has a second center frequency; and a difference between the first center frequency and the second center frequency exceeds a frequency difference threshold.
