摘要

宽带无线接入系统是大类共享介质接入系统的成员，其中单个中心站点通过单个传输介质与多个用户站通信。本文介绍了一种在固定BWA系统中与多个用户站共享单一传输介质的新方法，该方法支持语音/数据集成传输和动态带宽分配。给出了一种在3.5 GHz固定BWA系统中的MAC实现，重点研究了语音的动态接入技术。系统采用FDD/TDM/TDMA方式。本文最后给出了语音通过E1接口接入PSTN的框图。

Dynamic bandwidth allocation in fixed BWA systems

Broadband wireless access systems are members of a large class of shared medium access systems where a single central site communicates with multiple subscriber stations over a single transmission medium. This article introduces a novel method of sharing the single transmission medium with a number of subscriber stations in fixed BWA systems, which supports integrated voice/data transport and dynamic bandwidth allocation. A MAC implementation in 3.5 GHz fixed BWA system is given, which focuses on the dynamic access technology of voice. FDD/TDM/TDMA mode is applied in the system. In the end of this article, block diagrams describing how voice access PSTN through E1 interface are given.
