Overview of a more simplified new channel model to synthesize total attenuation time series for satellite communication systems at Ka and Q/V bands

To insure a favourable link budget in order to reach the required availabilities and to counteract severe propagation impairments, Fade Mitigation Techniques (FMT, such as adaptive coding [8, 9]) have to be implemented in the fixed satellites telecommunications systems. To develop, test and adjust the real-time algorithms of these adaptative FMTs, a good knowledge of the dynamics of the propagation channel is required and realistic attenuation time series are needed to feed system simulators. Unfortunately, the low number of available propagation experiments at Ka-band and above unavoidably leads to the use of channel models allowing synthetic total attenuation time series to be generated. The aim of this paper is first of all to present the justification of the parameterization used in Recommendation ITU-R P.1853–1 which has not been published in the open literature. Secondly, some limitations are highlighted before moving on an overview of a more simplified new channel model to synthesize total attenuation time series.
