Statistical Methods for Estimating Time and Rate Parameters of Digital Communication Systems
Edwin L. Crow
Abstract: Statistical methods are provided for estimating time and rate parameters of digital communication systems according to the specifications of the Proposed Federal Standard 1033. The methods may be applied to delay, disengagement, transfer and service times, and to transfer rates. Some ARPANET and Bell System data are examined for the form of distributions of times. The properties of various types of estimators are discussed, and the sample mean is recommended. Approximate confidence limits are given for time and rate parameters. A step-by-step procedure is provided for designing an experiment to estimate time and rate parameters with prescribed accuracy.
Keywords: ARPANET; autocorrelation; confidence limits; design of experiments; distribution-free estimation; robust estimation
