Abstract
A method of transmitting information is provided. The method is performed at a system for information transfer. The method includes obtaining a first symbol, in a predefined set of symbols, for transmission; determining a first frequency band, in a first set of frequency bands associated with the predefined set of symbols, that is associated with the first symbol; and transmitting a first signal pulse having a first frequency in the first frequency band. The method includes, after transmitting the first signal pulse, transmitting a control signal associating a second set of frequency bands with the predefined set of symbols. The second set of frequency bands is distinct from the first set of frequency bands. The method includes, after transmitting the control signal, obtaining a second symbol, in the predefined set of symbols, for transmission; determining a second frequency band, in the second set of frequency bands, associated with the second symbol; and transmitting a second signal pulse having a frequency in the second frequency band.
