ABSTRACT:
A method (20) and electronic device (1) for signal separation of mixed signals provided by sensors (11,13), the mixed signals resulting from the sensors (11,13) detecting respective mixed waveforms comprising a plurality of source waveforms originating from waveform generating sources mixed in a mixing environment (10). The method (20) and device (1), in use, provide for configuring (22) communication between a processor (3) and a plurality of the sensors (11,13) in the mixing environment (10), the configuring being effected dynamically depending upon variations in the number of sensors (11,13) in the environment. At a receiving step (23) the processor (3) receives respective mixed signals from the sensors (11,13) and a step of determining (24) un-mixing parameters for the environment based on the number of sensors (11,13) is then effected. Thereafter, a step of applying selectively (35) applies the un-mixing parameters to at least one of said mixed signals to thereby separate at least one of the mixed signals and provide at least one output source signal associated with one of the sensors (11,13), the output source signal being indicative of an unmixed one of the source waveforms.
