Abstract
A method of receiving information is provided. The method, performed at a system for information transfer, includes receiving a signal pulse and determining a frequency band and a pulse duration associated with the signal pulse. The method includes, in accordance with a determination that the frequency band is one of a set of frequency bands, determining, from a first set of symbols, a first symbol associated with the frequency band. The method also includes, in accordance with a determination that the pulse duration is one of a set of pulse durations, determining, from a distinct second set of symbols, a second symbol associated with the pulse duration. Each frequency band in the set of frequency bands is associated with a respective symbol in the first set of symbols, and each pulse duration in the set of pulse durations is associated with a respective symbol in the second set of symbols.
