“…It can be used for the calculation of the first (long term exceedance probability) and second order statistics (fade slope, fade durations, autocorrelation and hitting time statistics) of slant path rain attenuation with various electrical and geometrical characteristics. Moreover, the proposed model can be applied to the prediction of the performance of satellite fade mitigation techniques, such as Time diversity [20], or adaptive coding and modulation and power control. Also, with the extension of the model to multidimensional case [21], the proposed model can be used for interference analysis evaluation [22] and for the prediction of the fade margins for broadband wireless access networks [23].…”

In this paper, the dynamics of rain attenuation are examined, and dynamic diversity gain is evaluated for a pico-scale site diversity system. Since modern satellite communication systems operate at frequencies above 10 GHz, their efficient design requires the adoption of Propagation Impairment Mitigation techniques and so rain attenuation time series synthesizers. For rain attenuation, which is the most dominant fading mechanism, the dynamic stochastic model, proposed by Maseng-Bakken, based on the lognormal distribution is the most widely accepted and used. In this latter model, the dynamic parameter is required for the generation of slant path rain attenuation time series. In this paper, firstly, a simple expression is proposed for the calculation of the dynamic parameter in terms of the mean wind speed, elevation angle of the link, and dynamic parameter of rainfall rate. The new theoretical expression is tested with simulated data with very encouraging results. This expression is then used into a unified rain attenuation synthesizer with inputs from the rainfall rate statistics and the satellite slant path characteristics. Finally, the dynamic diversity gain is calculated for pico-scale site diversity systems for various link characteristics.

“…In particular, in the latter three references, i.e. [11][12][13], the joint statistics of rain attenuation for different time lags (waiting period) are modeled in order to be able to derive the outage probability of a system. In these three references, it is assumed that rain attenuation statistical behavior is approximated with lognormal distribution.…”

In this paper, a new model based on Copula functions for modeling joint exceedance probability of rain attenuation for time diversity satellite systems is presented. Time diversity is an efficient fade mitigation technique, which exploits the decrease of correlation of rainfall medium within time. Copulas theory is used for the coupling of rain attenuation random variables which are considered correlated. The performance of five Copulas on experimental time diversity data is investigated in this paper. The results are very encouraging. Moreover, a significant result is that different copulas must be used depending on the values of the considered time lags. Finally, some useful conclusions are drawn.

“…The CCDF parameters are found to be dependent on elevation angle and local climatology. Moreover, a new computation method of rain attenuation CCDF based on Maseng-Bakken stochastic dynamic model is presented in [12]. In tropical regions, a prediction model is proposed based on measured satellite beacon signal at 12 GHz in Malaysia; this model leads to find time diversity gain.…”

<p><span>This paper reports a study on mitigation of propagation impairments on Earth–space communication links. The study uses time diversity as a technique for mitigating rain propagation impairment in order to rectify rain fade. Rain attenuation time series along earth-to-satellite link were measured for two years period at 12.255 GHz in Malaysia. The time diversity technique was applied on measured rain fade to investigate the level of possible improvement in system. Time diversity gain from measured one-minute rain attenuation for two years period was estimated and significant improvement was observed with different delays of time. These findings will be utilized as a useful tool for link designers to apply time diversity as a rain fade mitigation technique in Earth-satellite communications systems.</span></p>
