We present the results from an analysis of GPS signals, exploiting the Doppler effect to monitor the behaviour and integrity of the GPS signals. The principle is simple: When a receiver is able to precisely determine the Doppler shift of the carrier

Applying the fractional Fourier transform (FRFT) and the Wigner distribution on a signal in a cascade fashion is equivalent to a rotation of the time and frequency parameters of the Wigner distribution. We presented in ter Morsche and Oonincx, 2002,

Applying the fractional Fourier transform (FRFT) and the Wigner distribution on a signal in a cascade fashion is equivalent with a rotation of the time and frequency parameters of the Wigner distribution. In this paper an integral representation form
