Alignment of multiple editions of a signal collected from multiple sensors

ACERDEC

Various embodiments associated with synchronization of signal editions from multiple sensors are described. A plurality of sensors can be deployed in an environment. Different copies of a desired signal can be present in the environment and there can be a desire to identify this signal even if the signal is unknown (and a demodulation scheme of the desired signal is not known). The plurality of sensors can sense weak editions of the desired signal and transfer those signals to a master sensor or to a separate location, such as a fusion center. The weak editions may be asynchronous due to the editions being captured at different locations, different channels, different devices, etc. At the master sensor or separate location, the weak editions can be post-synchronized together and then fused together into a strong signal. From the strong signal, a demodulation scheme can be determined and the signal can be demodulated.
