Harmonic Analysis, Signal Processing, and Complexity
In this paper we propose a method for blind signal decomposition that does not require the independence or stationarity of the sources. We define suitable quotients of linear combinations of the images of the mixtures in a given frame and we show experimentally that such quotients can be used to recursively extract three sources from only two measurements. A general strategy to extract more than three sources from two measurements is proposed.doi:10.1007/0-8176-4416-4_12 fatcat:fcjniwg3z5da3mqi7mkkdty23e
