Scintillation Fading Simulation.

Abstract

It is difficult to determine the long term effects of ionospheric scintillation on a particular modulation/coding scheme since the scintillation characteristics change rapidly. In order to measure the effect of the scintillation fading on the acquisition time, it would be necessary to repeat the acquisition test several hundred times. Since the acquisition of a modem such as the Dual UHF modem may take 1 to 5 minutes, it would be necessary to have scintillation fading for a period of 4 to 8 hours. The alternative is to record the UHF signal level of a simulator and reproduce a short segment of fading over and over again. This was done using the Avionics Laboratory Communication Systems Evaluation Laboratory (CSEL). (Author)
