A fast technique to simulate the effect of equatorial
ionospheric scintillation on GNSS signals was proposed by the
authors in a previous work. The algorithm uses a single-layer
phase-screen model of the ionosphere and the scintillation is
expressed by the Huygens-Fresnel (HF) integral which can be
determined analytically. Herein, we characterize statistically the
amplitude and phase obtained with the HF integral for different
values of the scintillation index S4. A phase unwrapper is also
developed to determine the phase from the modulo two-pi version
provided by the argument of the HF integral.
