Abstract: Comparisons of Fritchman's single-error-state model with the two-state Markov model are presented in graphical form for a number of statistical functions, e.g., the error gap distribution (EGD), the block error probability (BLER), and the probability of undetected block error (PUB). Measured data from previously published papers are shown on the curves where these are available, and examples of four types of channels are illustrated: HF, troposcatter, VHF, and switched network. A simple data-fitting procedure is described for the EGD, and its relationships to other statistics of interest are given.
