Rain rate and rain attenuation prediction for satellite communication in Ku and Ka bands over Nigeria

Rain rate and rain attenuation predictions are one of the vital steps to be considered when analyzing a microwave satellite communication links at the Ku and Ka bands. In this paper, tools for the prediction of rain rate and rain attenuation are presented in the form of contour maps for Nigeria using a massive rainfall data bank of 30 years which are taken from measurements made from the coast ...

Diurnal 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 ...

Rain Fade Compensation for Ka-Band Communications Satellites

Ka-BAND PULSED PROPAGATION THROUGH RAIN-FILLED ATMOSPHERE

An atmosphere of rain offers a dispersi e medium for the propagation of radio signals abo e 10 GHz. The effect of dispersion, in terms of differential attenuation and phase dispersion, is insignificant for narrowband signals. Signals modulated with ery short pulses can ha e a wide bandwidth o er which dispersion will be appreciable, causing significant signal distortion. The propagation of puls...
