摘要:

针对宽带数据链多业务传输的需求，提出了一种多速率异步复接技术，能有效地将视频、音频以及网络等不同速率数据进行复接。描述了多速率异步复接技术的层次结构，介绍了采用FPGA的实现方法，分析了采用此方案的实现效率，最后给出了仿真结果。该技术已在实际系统中应用，满足宽带数据链的使用要求，实现效率达97.2%以上。

Abstract:

A multirate asynchronous multiplexing technology is proposed to meet the deman d of mixedservice transmission of broad band datalink.With the technology,vide o, voice and other network data with different rate can be multiplexed efficiently. The hierarchy of multirate asyn chronous multiplex ing is described in detail,realization with FPGA is introduced,and the efficiency of this scheme is analysed. Finally，the simulation result is il lustrated.This method has been successfully applied in engineering and meets the requirement of broad band datalink.The multiplexing efficiency is over 97.2%.

Key words: broad band datalink multi rate asynchronous multiplexing video data audio da ta
