Abstract
Disclosed is a multiple sensor system including a plurality of different sensor devices to acquire respective signals sensed from a single signal source, and a signal acquisition apparatus to recover an original signal generated from the signal source. The signal acquisition apparatus recovers the original signal by applying joint recovery, based on characteristics and correlations between the respective sensor devices, to compressive sensing signals independently compressively sensed and transmitted from the respective sensor devices. At this time, a sensing matrix F prearranged with the respective sensor devices and channel information C between the original signal and each sensor device are used for joint recovery.
