According to the relevant documents of CCITT, a digital error impairment model of simple Poisson distribution and compound Poisson distribution is set up. Based on the probabilistic characteristics of Poisson distribution, a look up table method is derived and applied, which is especialy suitable for engineering application.The computer simultion shows that the results can closely approach the designated probabilistic distribution by this method. This paper provides theoretical and numerical basis for the implementation of digital error impairment simulator with simple Poisson and compound Poisson distribution.
