Research on Statistics and Simulation of Rain Attenuation Time Series at Microwave
The rain attenuation time series are simulated by the EMB model based on rain measured data and parameters at Haikou
Qingdao and Beijing.The power spectra estimated with simulative series are in good agreement with the measured result in references.The probability of fade exceeding a given fade duration value are calculated based on simulative attenuation time series
and compared with ITU-R predictive and measured values at 12.5GHz
in Haikou
Qingdao and Beijing.At Haikon
the statistics agree with predicted and measured results.At Beijing and Qingdao
as fade duration is less than about 100s
the simulative statistics are in agreement with measured results.As fade duration is more than about 100s
there are the difference among them.At 30/20GHz
for the smaller fade threshold and duration
the statistics based on simulation approach to the results predicted by ITU-R.As the larger fade threshold and duration
the statistical results by simulation are different to the prediction statistics by ITU-R.The results show that the simulation method is available for the rain region of abundant rainfall.However
at insufficient rainfall region
the method or ITU-R prediction may be modified as longer fade duration.It is significant groundwork for rain fade mitigation techniques development in higher frequency wireless systems.
