Abstract:
In the paper "Impulse generation with appropriate amplitude, length, inter-arrival, and spectral characteristics," by I.Mann et.al., [1] the authors present what the guest editors believe is the most recent statistical model of nonstationary impulse noise. The Henkel/Kessler (HK) model discussed in that paper proved to be a good fit for all measured impulse noise voltage amplitude distributions collected in both the networks of Deutsche Telekom (DT) and British Telecom (BT). Nevertheless, in order to facilitate the use of the results of Tough and Ward [3] on random noise generation with prescribed amplitude and spectral characteristics, a Weibull type density was investigated as a possible alternative since it simplfies an approximate realization of the stochastically varying spectral properties. The authors recognized that HK model is a better fit than the Weibull density and can be considerd as more realistic while suggesting that in further studies the Tough-Ward method for the DT data sets will be finalized. This paper proposes a suitable method for simulating impulse noise with Henkel/Kessler amplitude probability density function and impulse length according a stable probability density function.
