F. Vatalaro et A. Forcella, DOPPLER SPECTRUM IN MOBILE-TO-MOBILE COMMUNICATIONS IN THE PRESENCE OF 3-DIMENSIONAL MULTIPATH SCATTERING, IEEE transactions on vehicular technology, 46(1), 1997, pp. 213-219
This paper provides analytical expressions for the time-autocorrelatio
n function and the Doppler spectrum in a mobile radio channel in the p
resence of three-dimensional (3-D) multipath scattering, Mathematical
modeling of the transmission channel is based on the assumption of wid
e-sense stationary (WSS) scattering, This paper deals with the case of
a mobile-to-mobile radio link and derives formulas for the mobile-to-
radiobase link as a special case, The Doppler spectrum examples provid
ed are typical when assuming mobile terminal(s) located in densely bui
lt-up urban areas and simple dipole terminal antenna(s). Furthermore,
the Doppler spectrum for transmission between a nongeostationary satel
lite and a mobile terminal located on the ground is analyzed, If diffe
rent antenna patterns are to be considered and detailed knowledge is a
vailable on the multipath distribution, realistic Doppler spectra may
be calculated using the approach presented in this paper.
