On sparse approximations of solutions to linear systems with orthogonal matrices

This article discusses a model for obtaining a sparse representation of a signal vector in ℝk, based on a system of linear equations with an orthogonal matrix. Such a representation minimizes a target function that combines the deviation from the exact solution and a chosen functional J. The functio...
