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 and a first pulse duration associated with the first signal pulse. The method includes, in accordance with a determination that the first frequency band is one of a predefined set of frequency bands, and that the first pulse duration is one of a predefined set of pulse durations, determining, from a predefined set of symbols, a first symbol associated with the first frequency band and the first pulse duration. Each frequency band in the predefined set of frequency bands is associated with a respective set of two or more symbols, and each symbol of a respective set of two or more symbols is associated with a distinct respective pulse duration in the first predefined set of pulse durations.
