Alignment of signal copies from an asynchronous sensor network

A non-transitory computer-readable medium configured to store computer-executable instructions that when executed by a processor cause the processor to perform a method, the method comprising:

• receiving a first signal copy of a signal of interest from a first sensor, where the first signal copy is a digital signal sampled at a first sampling time period;
• receiving a second signal copy of the signal of interest from a second sensor, where the second signal copy is a digital signal sampled at a second sampling time period, where the first sampling time period is different from the second sampling time period, where the first sensor and second sensor are different sensors, and where the first sensor and second sensor are asynchronous;
• identifying the first sampling time period;
• estimating and resampling the second signal copy in accordance with the first sampling time period to produce a resampled second signal copy, where the resampled second signal copy and the first signal copy have the same sampling time period;
• fusing the first signal copy and the resampled second signal copy into a fused signal copy of the signal of interest;
• matching the fused copy of the signal of interest with a known signal;
• identifying a modulation scheme associated with the known signal;
• demodulating the fused copy of the signal of interest through use of the modulation scheme;
• and
• outputting the signal of interest after demodulation.

A system, comprising:

• an identification component configured to identify a first signal copy as a reference signal, where the first signal copy is a copy of a signal of interest, where the first signal copy is a digital signal sampled at a first sampling time period, and where a network of the signal of interest is unknown to the system;
• a resample component configured to resample a second signal copy of the signal of interest in accordance with the first sampling time period to produce a resampled second signal copy, where the second signal copy is a digital signal sampled at a second sampling time period and where the first sampling time period and the second sampling time period are different;
• a fusion component configured to fuse the first signal copy with the resampled second signal copy into a fused copy of the signal of interest;
• and
• a demodulation component configured to perform a demodulation on the fused copy of the signal of interest.
