A Test for the Validity of the Generalized Gilbert Model Using Real Communications Channels

摘要

A proposal has been made to use the generalized Gilbert model in a real time channel monitoring device. The purpose of the device is to calculate error statistics by observing an operational channel and, from the observations, estimate the model parameters. The parameter estimates can then be used to calculate the desired channel statistics. An estimator is developed which yields these parameters. The estimator and the model are tested using real communications channels. The model and/or estimator are found to be invalid when applied to the channel data available. A sensitivity analysis is conducted using the probability equations associated with the model. The sensitivity study indicates that the parameters of the generalized Gilbert model cannot be uniquely, simultaneously estimated from observations of the data. (Author)
