Abstract

The embodiment of invention discloses a SDH signal transmission method, a device and a system, which relate to wireless communication field and can solve the problem that when a PDH signal is multiplexed with a SDH signal, the generated bandwidth is insufficient. The SDH signal transmitting method includes that SDH container in SDH signal is simplified through stuffing byte or cost reduction; the SDH signal with simplified SDH container is transmitted. The SDH signal receiving method includes that a SDH signal is received, and the simplified SDH container of the SDH signal is recovered through the recovery of stuffing byte or cost. The embodiment of invention is applicable to SDH transmission in wireless communication field.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to a method, device and system for transmitting synchronous digital sequence signals. Background technique [0002] In a digital communication system, the transmitted signals are digitized pulse trains. When these digital signal streams are transmitted between digital switching devices, their rates must be completely consistent to ensure the accuracy of information transmission, which is called synchronization. In the digital transmission system, there are two digital transmission series, one is called PDH (Plesiochronous Digital Hierarchy, quasi-synchronous digital series), and the other is called SDH (Synchronous Digital Hierarchy, synchronous digital series). [0003] In the system using PDH, high-precision clocks are set on each node of the digital communication network, and the signals of these clocks have a unified standard rate. Although the precision of each c...
