Abstract: A general model of received signal variability is outlined in which the signal level is represented as a simple algebraic combination of random functions which, in turn, vary with time, location, and the "situation." A study of signal variability should then be a study of the statistics of these separate random functions. Among other things, the model inspires extended definitions of the terms "reliability" and "confidence."
