The purpose of this study is to determine whether the error cause present in a modem or channel can be ascertained using the parameters of matrix and renewal models of the digital channel. Data generated by a modem subjected to three major error causes, impulse hits, frequency offset, and phase jitter, were supplied by the Digital Communications Experimental Facility DICEF, Rome Air Development Center, Griffiss AFB, New York. A simulator was used to produce the error cause in the model or channel. The parameters for Fritchmans partitioned Markov chain model, the parameters of the renewal channel model of Muntner and Wolf, and the stationary distribution and stationarity of the transition probabilities for the error-free run model are used to determine the cause of errors. This study indicates that they can be used for this purpose. Author
