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...
متن کاملDiurnal variation of slant path Ka-band rain attenuation at four tropical locations in India
Rain attenuation is very severe at Ka and higher frequencies especially in tropical regions. The conventional fade mitigation techniques are not be able to mitigate this severe fade and hence, suitable diversity technique is required for this purpose. In this paper, rain characteristics and slant path rain attenuation at 30 GHz using synthetic storm technique has been presented. Three years of ...
متن کاملImproving Rain Attenuation Estimation: Mod- Elling of Effective Path Length Using Ku- Band Measurements at a Tropical Location
Rain attenuation is an important aspect of signal propagation above 10GHz frequency. The attenuation time series generation from point rain rate measurement is crucial due to unavailability of actual signal measurements. In this paper, a simple and realistic approach has been demonstrated for better estimation of rain attenuation using Ku-band signal propagation data and ground rain rate measur...
متن کاملMaximum-likelihood estimation of specific differential phase and attenuation in rain
Precise estimation of propagation parameters in precipitation media is of interest to improve the performance of communications systems and in remote sensing applications. In this paper, we present maximum-likelihood estimators of specific attenuation and specific differential phase in rain. The model used for obtaining the cited estimators assumes coherent propagation, reflection symmetry of t...
متن کاملSimple and accurate analytical calculation of shortest path lengths
We present an analytical approach to calculating the distribution of shortest paths lengths (also called intervertex distances, or geodesic paths) between nodes in unweighted undirected networks. We obtain very accurate results for synthetic random networks with specified degree distribution (the so-called configuration model networks). Our method allows us to accurately predict the distributio...
