Abstract
A method for reducing the noise in data-sets of harmonic signals that include data vectors X of length L, with each data vector X including P harmonic components is described. The method includes the steps of computing a Hankel matrix H by applying the equation (Hij)=(Xi+j−1); estimating a matrix Y by estimating the product of the Hankel matrix H by a matrix Ω, the matrix Ω including a set of K random unit vectors; computing an orthogonal matrix Q by performing a QR decomposition on the matrix Y and then computing the conjugate and transpose matrix Q* of the orthogonal matrix Q; estimating a K-ranked approximation {tilde over (H)} of the Hankel matrix H; and estimating (500) reduced noise data vectors X from the estimated K-ranked approximation {tilde over (H)} of the Hankel matrix H.
