Average bit error rate for satellite uplink communications in Ka-band under atmospheric turbulence given by Gaussian model

We study the influence of atmospheric turbulence on satellite communications by the theoretical analysis of propagation characteristics of electromagnetic waves through inhomogeneous random media. The analysis is done by using the moment of wave fields given on the basis of a multiple scattering method. We analyze the average bit error rate (BER) which is derived from the probability density function of a received intensity for the Geostationary Earth Orbit (GEO) satellite uplink communications in Ka-band under atmospheric turbulence whose statistical characteristics are given by the Gaussian model. From the analysis, we find that the degradation in BER for the uplink communications is caused by spot dancing of received wave beams due to atmospheric turbulence at low elevation angles when wave beams are transmitted from a large aperture antenna.
