A method for statistical wavelet analysis of ionospheric GPS signals

A technique of statistical wavelet analysis is proposed and tested for applicability to the data of radio sounding of the ionosphere by navigation signals of the global positioning system. Important advantages of wavelet analysis over spectral analysis are demonstrated, including performance under short-term fault conditions.
