Abstract:

Computer graphics have been incorporated into a model evaluation software package that is intended to provide insight into the statistics of propagation loss. Specifically, the user may optionally superimpose plots of theoretical distribution curves on empirical distribution displays. A tutorial review of the gamma distribution is presented in the context of multipath fluctuations, followed by a comprehensive discussion of the log-transformed gamma distribution. An example is included to illustrate the application of the maximum likelihood method of parameter estimation. Author
