SIGNAL COMPRESSION BY MEANS OF THE TIKHONOV REGULARIZATION METHOD
ABSTRACT
Application of the Tikhonov regularization method in the problem of signal compression by discrete orthogonal transformations is investigated. This problem is investigated as an ill-posed problem. Regularization parameters for different discrete orthogonal transformations (DOTs) are found. Matrices for selection of spectral components for different DOTs are determined. Errors of recovery of a compressed signal, coded by orthogonal transformations with and without regularization, are evaluated. From these evaluations it stems that a signal, recovered by the Tikhonov regularization method, is closer to the reference signal than a signal recovered without application of a regularization method.
