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...
متن کاملStatistical 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...
متن کاملEarth-Space Links and Fade-Duration Statistics
In recent years, fade-duration statistics have been the subject of several experimental investigations. A good knowledge of the fade-duration distribution is important for the assessment of a satellite communication system's channel dynamics: What is a typical link outage duration? How often do link outages exceeding a given duration occur? Unfortunately there is yet no model that can universal...
متن کاملMicrowave Attenuation Studies Due to Rain for Communication Links Operating in Malaysia
Attenuation due to rain is an important constraint in the designing of the microwave communications links operating in Malaysia especially at frequencies above 10 GHz. In recent studies, the ITU-R proposed models for the prediction of rain attenuation give a good estimation for the microwave propagation loss caused by rain for the temperate regions but it underestimates the rain attenuation pre...
متن کاملReliability Analysis of FSO Communication Links Using Aberrated Divergent rectangular Partially Coherent Flat- Topped Beam
The effects of aberration on the Bit-Error-Rate (BER) and reliability of free- space optical (FSO) communication links are investigated. Based on aberrated divergent rectangular partially coherent flat-topped beam formula on the receiver plane and considering the atmosphere losses due to absorption and scattering, numerical values for Power In Bucket (PIB), Signal to Noise Ratio (SNR) and BER a...
