Abstract

A system processes data signals consisting of sums of independent signal terms, zero or more of which signal terms may already have been identified, in order to generate one or more additional terms. Deflated versions of the data signals are created by subtracting from the data signals any previously identified signal terms. Additional independent signal terms are computed using a set of reference signals organized into mutually independent partioning support sets. The images of each support set are computed on the data signals. Computed images on a data signal that are non-zero are identified as additional independent signal terms of that data signal.

Dependent claims

A method for generating at least one deflated data signal from a set of original data signals, the method for use with at least one support set, wherein:

a. the at least one support set comprises at least one reference signal;
b. the at least one support set is a partitioning support set of a first subset of at least one original data signal wherein the at least one original data signal is an instantaneous sum of a plurality of independent signal terms;
and
c. the at least one reference signal in the at least one support set is coherent with an independent signal term of at least one signal in a second subset of at least one original data signal;
and
the method performed by at least one computer processor executing computer program instructions stored on at least one non-transitory computer-readable medium, the method comprising:
(A) generating an image and a residue of the at least one support set on a corresponding one of the at least one signal in the first subset;
and
(B) selecting, as the at least one deflated data signal, at least one of the image and the residue, wherein the at least one deflated data signal is incoherent with at least one of the plurality of independent signal terms of the first subset.

and
the method performed by at least one computer processor executing computer program instructions stored on at least one non-transitory computer-readable medium, the method comprising:
(A) generating an image and a residue of the at least one support set on a corresponding one of the at least one signal in the first subset;
and
(B) selecting, as the at least one deflated data signal, at least one of the image and the residue, wherein the at least one deflated data signal is incoherent with at least one of the plurality of independent signal terms of the first subset.
