The primary goal of this work is to summarize spectral meth-
ods to estimate the time delay variations of the detrended Medium
Scale Traveling Ionospheric Disturbances (MSTIDs) signals and pre-
liminarily discuss the ...

The purpose of this paper is to characterize Medium Scale Trav-
eling Ionospheric Disturbances (MSTIDs), by means of Mixed Integer
Nonlinear Programming (MINLP). The MINLP techniques are used
to for estimating the ...

In this paper we discuss the e ects of several signal preprocessing
methods for enhancing the Medium Scale Traveling Ionospheric Dis-
turbances (MSTIDs) signal. The MSTIDs signal are the ionospheric
signatures of waves ...
