Observation of L band equatorial scintillation

Abstract

This paper studies on Ionospheric scintillation at 1.5GHz. The observed scintillation data received at Bangkok were taken during this solar maximum cycle and covered two ionospheric scintillation locations, POR and IOR. The study includes the cumulative distribution function of the signal and also signal statistics such as the decibel levels of maximum peak, 5% peak, maximum fade and 95% fade, in addition, compared with scintillation index S_4. This paper also presents empirical relation between fading level and S_4 and the power spectrum of scintillation event.
