  • INFORMATION TRANSFER USING DISCRETE-FREQUENCY SIGNALS AND INSTANTANEOUS FREQUENCY MEASUREMENT
    Publication number: 20200328830
    Abstract: A method of receiving information is provided. The method is performed at a system for information transfer. The method 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 predefined set of frequency bands, determining, from a predefined set of symbols, a first symbol associated with the first frequency band and represented by the first signal pulse. Each frequency band in the predefined set of frequency bands is associated with a distinct respective symbol in the predefined set of symbols, and frequency bands in the predefined set of frequency bands, in aggregate, are not contiguous.
