How to estimate the impact of burst packet loss on speech quality in packet network of Electric Power Utility

چکیده
In this paper influence of burst packet loss on the quality of telephony speech signal in the packet network of Electric Power Utility (EPU) is calculated. Due to transients, the burst packet loss in EPU network is more probable than random packet loss. We can calculate the impairment factor in two ways: as the mean value of impairments in all nodes, or as the impairment for the mean value of burst duration in the network. Jensen's inequality is used to prove that the second method of calculation gives the pessimistic (conservative) estimate of the speech signal impairment. Streszczenie. W artykule analizuje się wpływ utraty pakietu na jakość telefonicznego sygnału w pakietowej sieci EPU. Rozerwanie pakietu jest bardziej prawdopodobne niż przypadkowa strata pakietu. Analizowano współczynnik zniekształcenia na dwa sposoby: jako średnia wartość zniekształceń we wszystkich węzłach lub średnia wartość trwania zniekształcenia. (Jak określić wpływ utraty pakietu na jakość rozmowy w pakietowej sieci EPU)

Design and Practical Implementation of a New Markov Model Predictive Controller for Variable Communication Packet Loss in Network Control Systems
The current paper investigates the influence of packet losses in network control systems (NCS’s) using the model predictive control (MPC) strategy. The study focuses on two main network packet losses due to sensor to controller and controller to actuator along the communication paths. A new Markov-based method is employed to recursively estimate the probability of time delay in controller to ac...
