Research And Design Of Sending And Receiving Data Mechanism Within High Speed Radio Based On Linux

In modern warfare, the communications network of the enemy is the primary attacked target, without them, the latest frontline progress of a battle and intention can not be effectively passed on. However by military radio, commanders can learn the latest and most accurate information from frontline which commanders can send down timely. With the development of science and technology, modern warfare become more and more fiercer, the situation more and more complicated, So battlefield interactive information increase exponently, in this case, study and design a new generation of highspeed military radio is particularly important.This paper have finished designing and developing of sending and receiving data within the high-speed radio.First of all, it descript the important part the high-speed radia can play, then tell the necessity of designing and developing job. Secondly, it has designed framework of sending and receiving within the high-speed radio base on Linux OS according to specific request. At the same time make a introduction relevant theory and reason. Thirdly, explain what the development board of RIOV₂478 control board software and hardware developmenting environment is. At one hand lay particular emphasis on Yocto project and with its ways to configure and compile Linux system image. On the other hand state how to download various Linux image to development board. At last, this text introduce the method and steps of designing and developing virtual networke card driven in linux. First explain some knowledge of the principles used in the virtual NIC and two important structures of NIC driver, then invent the virtual NIC driven combine the real NIC driven. At last, test and analyze the network reciving and sending of radio.
