Simulation Studies for Data Multiplexing in Speech with Stdm or Tasi

Abstract

A simulation model of a finite buffer queueing system with Erlang arrivals and multiple random servers is presented. The number of active servers in a service interval vary through a birth and death process derived from the speech samples in synchronous time division multiplexing (STDM) or time assignment speech interpolation (TASI) system. The results of this study show that the TASI system requires a larger buffer than the STDM system for a specified overflow probability.
