Abstract
The devices and methods leverage harmonics to resolve, separate, and identify devices. The devices and methods use the harmonic patterns associated with a frequency modulating (FM) signal to discern and extract information from the FM signal using correlation learning in a crowded spectrum space where the nodes are transmitting simultaneously on multiple channels. The methods and devices leverage harmonics to resolve, separate, and/or identify wireless communication devices.
Claims18
A receiver, comprising:
- an antenna;
- one or more processors;
- memory in electronic communication with the one or more processors;
- and
- instructions stored in the memory, the instructions executable by the one or more processors to:
- receive a plurality of signals from a plurality of sensors in communication with the receiver, wherein each sensor of the plurality of sensors is allocated a non-overlapping frequency band for communicating with the receiver;
- correlate, to each signal of the plurality of signals, a fundamental frequency signal and a harmonic pattern;
- and
- use the harmonic pattern correlated to the signal to identify a sensor of the plurality of sensors that sent the signal.
A method of device identification performed by a receiver, comprising:
- receiving a plurality of signals from a plurality of sensors in communication with the receiver, wherein each sensor of the plurality of sensors is allocated a non-overlapping frequency band for communicating with the receiver;
- correlating, to each signal of the plurality of signals, a fundamental frequency signal with a harmonic pattern;
- and
- using the harmonic pattern correlated to the signal to identify a sensor of the plurality of sensors that sent the signal.
