Abstract:
Theoretical expressions for joint probability-density and distribution functions for phase difference and log-envelope difference for a Gaussian channel are derived. Experimental data collected from an HF phase-stable transmission are compared with the theoretical densities and distributions by using the statistical parameter of correlation coefficient. An estimate of the relationship between the correlation coefficient and channel frequency spread is derived and compared with experimental data. Agreement between correlation-coefficient estimates from log-envelope change and phase change is discussed. The experimental envelope distributions of the received signal are compared with the Rayleigh, Rician, and log-normal distributions, and deviations are discussed. Alternative envelope distributions based on a conditional Rayleigh distribution are also considered. Author
