abstract = "Equatorial ionospheric scintillation is a phenomenon that occurs
frequently, typically during nighttime, affecting radio signals
that propagate through the ionosphere. Depending on the temporal
and spatial distribution, ionospheric scintillation can represent
a problem in the availability and precision for the Global
Navigation Satellite System's users. This work is concerned with
the statistical evaluation of the amplitude ionospheric
scintillation fading events, namely, level crossing rate (LCR) and
average fading duration (AFD). Using ±-¼ model, the LCR and AFD
are validated against experimental data obtained in S{\~a}o
Jos{\'e} dos Campos (23.1S; 45.8W; dip latitude 17.3S), Brazil, a
station located near the southern crest of the ionospheric
equatorial ionization anomaly. The amplitude scintillation data
were collected between December 2001 and January 2002, a period of
high solar flux conditions. The obtained results with the proposed
model fitted quite well with the experimental data and performed
better when compared to the widely used Nakagami-m model.
Additionally, this work discusses the estimation of ± and ¼
parameters, and the best fading coefficients found in this
analysis are related to scintillation severity. Finally, for
theoretical situations in which no set of experimental data are
available, this work also presents parameterized equations to
describe these fading statistics properly. Key Points A model is
proposed for second order statistics of ionospheric scintillation
The model is validated using a large data set from the last solar
maximum period A series of equations and approximations for
