ABSTRACT:
A signal separation method for separation of source signals from a composite signal expresses the composite signal as a series of values of signal amplitude. The source signals have periodicities similar or equal to p. The composite signal is portioned into sections which provide respective rows of a matrix X, in which successive rows represent successive sections. A singular value decomposition of the matrix X is performed to obtain two singular vector matrices U, V and a singular value matrix λ. An independent component analysis is performed on one of the singular vector matrices U, V to obtain an independent component matrix UR2T,R1TV and an associated component matrix R2λV,UλR1. One of the component matrices UR2T,UλR1contains estimated separated signal modulation envelopes and the other component matrix R2λV, R1TV contains estimated separated cyclets.
