A class of aeronautical wide-band channel models
is proposed, featuring parking and taxi environments, takeoff
and landing situations, and en-route scenarios for ground–air
and air–air links. Typical and worst case parameter sets are
suggested, based on published measurement results and empirical
data. The models are suitable for channel emulators that can
be easily implemented on digital computers or in hardware and
thus are useful for the validation of digital aeronautical links.
A time-domain and frequency-domain implementation of such
a channel emulator are derived, and results for a typical multicarrier
system are presented. It is shown that the scenarios have
distinguishable performance results depending on the underlying
maximum ranges and shapes of the Doppler and delay spectra and
the presence of a line-of-sight path. Finally, the degrading effects
of intersymbol interference and intersubcarrier interference on
the multicarrier signal are explained.
