Modelling And Detection of Rain Attenuation For MF-TDMA Satellite Networks Utilizing Fade Mitigation Techniques

Whilst the ability to characterise the on-average monthly or yearly performance of systems without countermeasures is well determined, such methods are not efficient at Ka-band and above. Optimal fade mitigation technique design requires statistically and dynamically correct attenuation time-series. Optimal allocation of communication resources requires consideration of the channel statistics a...

Estimation of rain induced attenuation on earth- space path

This paper describes research on earth-space attenuation on a microwave communications link set up at Belgaum-RC Nagar (Karnataka State), India, during July to September, each year. The rain data secured from India Meteorological Department, Bangalore has been used for analysis with the live data of rainfall recorded with the aid of two tipping bucket rain gauges, and a disdrometer. A simple mo...

Statistical Analysis of Rain Fade Slope

An analysis is made of the measured distributions of the fade slope of rain attenuation, conditional for attenuation values, measured at Eindhoven University of Technology from the satellite Olympus. It is found that the distribution is similar for positive and negative fade slopes and independent of frequency in the range from 12 to 30 GHz. A distribution model for the conditional distribution...

Statistical Analysis of Rain Fade Slope

The fade slope is a stochastic parameter and varies with time. The probability distribution of fade slope can depend on attenuation, on the drop size distribution and therefore on the type of rain, and on the wind velocity perpendicular to the path. Furthermore, if several rain cells and/or different kinds of rain may be present, the fade slope is likely to decrease with path length, and theref...
