Comparison of Signal Scintillation Models.

Abstract

Scintillating signals taken from the DNA Wideband satellite experiment are used as direct input to a digital simulation of a phase-shift keyed (PSK) demodulator. The resulting demodulator performance is compared to that obtained with input signals generated according to a two-component (log-normal plus joint Gaussian) model. A second comparison is made with input signals generated by a multiple phase screen propagation simulation. Results are used to assess the suitability of the models for simulation of satellite communication systems in disturbed environments. (Author)
