| Abstract: |
| A multirate asynchronous multiplexing technology is proposed to meet the deman
d of mixedservice 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 multirate 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%. |
