1. A method, comprising:

  • receiving a matrix comprising a first plurality of samples associated with a first signal and a second plurality of samples associated with a second signal, the second signal comprising a first portion associated with the first signal and a second portion associated with at least one disturbance;

    projecting the matrix into an orthogonal space;

    using the projected matrix to at least partially isolate the first portion of the second signal from the second portion of the second signal; and

    generating and storing a model associating the first signal and the isolated first portion of the second signal;

    wherein the matrix comprises (i) a first column Hankel matrix comprising the first plurality of samples in a first portion of the matrix and (ii) a second column Hankel matrix comprising the second plurality of samples in a second portion of the matrix; and

    wherein the first column Hankel matrix comprises one of a backward column Hankel matrix and a forward column Hankel matrix, and the second column Hankel matrix comprises one of a backward column Hankel matrix and a forward column Hankel matrix.
