数字基带电话系统的时分复用研究

A Research on Time Division Multiplexing for Digital Telephony System

为保障时分复用系统工作在无码间干扰的状态下,通过对PCM基带复用系统的原理分析,并结合单路基带系统码间干扰的消除方法,给出了不同复用制式消除码间干扰时传码率与系统带宽之间的关系,从而为设计不同制式数字基带电话系统提供了一定的理论指导。

In order to eliminate intersymbol interference of time-division multiplexing system,this paper explains the relation of system bandwidth and transmission speed in all kinds of multiplexing modes,by analyzing the principle of PCM baseband multiplexing system and the method of eliminating intersymbol interference in the single baseband system, and a guidance of theory is provided for designing different modes of digital telephony system.
