摘要：
The present invention relates to a device (22) for processing input signals (34a, 34b) related to a vital sign of a subject (10), comprising an interface (24) for receiving a non-invasively detected input signal (34a, 34b), a feature extraction module (26) for extracting at least one feature of the input signal (34a, 34b), said at least one feature including an instantaneous frequency representation (40a, 40b) of the input signal (34a, 34b) and/or an instantaneous amplitude representation (42a, 42b) of the input signal (34a, 34b), a processing module (28) for determining a signal information content parameter (52) for the input signal (34a, 34b) based on the at least one extracted feature, said signal information content parameter (52) being indicative of information on a vital sign of the subject (10) included in the input signal (34a, 34b) and a combination module (30) for combining a plurality of input signals based on the signal information content parameters (52) of the plurality of input signals into a combined output signal characterizing the vital sign of the subject (10). The present invention further relates to a corresponding method and to a monitoring system (12) for remotely monitoring a vital sign of a subject (10).
