Abstract:
1. A processing device comprising: interface circuitry configured to receive compressive measurements of a signal from respective ones of a subset of a plurality of sensors and to receive a non-compressive measurement of the signal from at least a given one of the sensors not in the subset; a delay determination module configured to process the compressive measurements in order to determine time delays between arrivals of the signal at different ones of the sensors; and a source localization module configured to determine a location of a source of the signal based on the time delays; wherein the delay determination module is configured to determine respective time delays between arrivals of the signal at different ones of the sensors based at least in part on respective impulse response vectors, the respective impulse response vectors being sparse vectors characterizing impulse responses of respective channels between the signal source and respective ones of the sensors; and wherein the delay determination module is configured to compute respective ones of the impulse response vectors using the non-compressive measurement and a corresponding one of the compressive measurements.
