ABSTRACT
Wideband applications become still more important in
terrestrial microwave communications nowadays. Propagation
conditions significantly affect the quality of
microwave communication systems. In order to assess
the influence of inhomogeneous atmosphere on the propagation
conditions, simulations of electromagnetic wave
propagation are utilized. A parabolic equation method
(PEM) is often applied for the purpose of terrestrial
microwave simulations. This method can calculate single
frequency response efficiently. This paper deals with
an application of an interpolation technique to speed
the calculation of a wideband frequency response at one
receiver point. A complex received signal is modeled as
the weighted sum of complex exponentials. The complex
exponential model parameters are extracted by means of
the matrix pencil method. Numerical examples of the
application of the method are introduced. Results are
compared with the channel transfer functions computed
using repeated PEM sim ..
