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.
Claims14
A method performed by a receiver for correlating a harmonic pattern to a received signal, comprising:
- determining a plurality of nodes in a targeted area in communication with the receiver;
- designing a non-overlapping fundamental frequency spectrum for each node of the plurality of nodes to communicate with the receiver;
- generating a set of harmonic patterns for each node of the plurality of nodes based on the non-overlapping fundamental frequency spectrum;
- and
- correlating the set of harmonic patterns with received signals from the plurality of nodes.
A receiver, comprising:
- an antenna;
- a processor;
- memory in electronic communication with the processor;
- and
- instructions stored in the memory, the instructions executable by the processor to:
- determine a plurality of nodes in a targeted area in communication with the receiver;
- design a non-overlapping fundamental frequency spectrum for each node of the plurality of nodes to communicate with the receiver;
- generate a set of harmonic patterns for each node of the plurality of nodes based on the non-overlapping fundamental frequency spectrum;
- and
- correlate the set of harmonic patterns with received signals from the plurality of nodes.
