Scintillation Prediction Models Compared with One Year of Measurements in Aveiro, Portugal

The paper presents new scintillation statistical results measured at Ka-band in the Iberian peninsula, where data is relatively scarce. The receiver is installed at Aveiro (8degW, 40.5degN), Portugal, and is pointed to HotBird-6 satellite. The data was collected at a rate of 8 S/s during one full year. Results for cumulative distribution of scintillation amplitude (fades and enhancements), scintillation intensity and diurnal variation are presented. The performance of some well known models in the literature - ITU, Karasawa and van de Kamp - are evaluated against the experimental data.
