摘要
本文应用马氏过程的方法对带延迟传送措施的话音插空系统的冻结剪音(Freezeout)进行了分析,得到系统的冻结剪音概率与延迟时长的关系.分析结果优于应用排队论方法的情况.从而证明采用一定时长的延迟措施后,即可使这一系统指标达到令人满意的程度.
This paper applies the theory of Markovian process to the analysis of TASI system with speech delay and exposes the relation between the Freezeout probability and the speech delay.The result of analysis is better than that obtained by the queueing theory.It is there by proven that the performance of system will be satisfied by properly adjusting the speech delay.
