Prediction of Rain Attenuation Series with Discretized Spectral Model
The rain attenuation plays a major role in the design of satellite-to-earth links operating at high frequencies such as Ka band and Ku band. The signal suffers from a strong attenuation during the propagation path as raindrops absorb and scatter radio waves, which results in an increase of transmission error and reduction of the system availability [1]. Predicting rain attenuation is one of the...
متن کاملShort-term prediction of rain attenuation using financial time series models
The constant demand for increased capacity of communication channels has led the SATCOM industry to develop new satellite systems operating at frequencies above 20 GHz where large bandwidths are available (EHF band – Extremely High Frequencies). Nevertheless, attenuation effects of atmospheric gases, clouds and rain can reach significant levels at these frequencies and it is no longer cost-effe...
متن کاملRain Attenuation at Terahertz
Rain attenuation values were calculated using empirical raindrop-size distributions, which were, Marshall-Palmer (M-P), Best, Polyakova-Shifrin (P-S) and Weibull raindrop-size distributions, and also calculated using a specific rain attenuation model for prediction methods recommended by ITU-R. Measurements of Terahertz wave taken at 313 GHz (0.96 mm) were compared with our calculations. Result...
متن کاملDetecting Rhythms in Time Series with RAIN
A fundamental problem in research on biological rhythms is that of detecting and assessing the significance of rhythms in large sets of data. Classic methods based on Fourier theory are often hampered by the complex and unpredictable characteristics of experimental and biological noise. Robust nonparametric methods are available but are limited to specific wave forms. We present RAIN, a robust ...
