RYBAKOV, A.S., 2014. Sampling and recovery of angle-modulated signals on the basis of the compressed sensing and event timing techniques. Automatic Control and Computer Sciences, 48(3), pp. 167-179.
Informative parameters of angle-modulated signals evaluated by the zero-crossing time instants are studied. Specific features of the compressed sensing technique used to restore modulating signals are considered. It is shown that the standard compressed signal processing techniques based on the minimization do not enable the solution of the problem of the off-the-grid recovery of spectral components. It is proposed to use an iterative method for signal recovery based on successive localization of the spectral peaks between the grid nodes. © 2014 Allerton Press, Inc.
