Abstract

Tropospheric scintillation is the rapid fluctuation and degradation of satellite signals due to changes in refractive index of atmosphere. This phenomenon tends to affect signals more strongly at frequencies above 10 GHz. This paper introduces a new scintillation prediction model created by modifying the existing Karasawa model. The proposed model is compared with currently existing model using scintillation data collected in Parit Buntar, Malaysia. The proposed model can simultaneously predict scintillation intensity of both fade and enhancement scintillation with an error rate below 5 %.
