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
