数字微波通信中的多链路传输技术

摘要

With the development of telecommunication, there are more bandwidth requirements in microwave communication. In this paper, multi-link PPP, inverse multiplexing ATM, visual concatenation and E1 inverse multiplexing techniques were analyzed in detail, which are suitable of different cases of microwave transmission, and can make fully use of original low bandwidth resources to increase relative transmission speed and bandwidth efficiency.%通信的发展对当前的数字微波通信提出了更高的带宽扩充需求，本文详细分析了多链路PPP技术、反向复用ATM技术、虚级联技术和E1反向复用技术等多链路传输方法及其基本原理，这些技术适用于不同的微波传输情况，可以在最大效率利用原有低速资源的条件下，提高相应的传输速率和信道带宽利用率。
