Research Of Turbo Code In Airborne Data Link

With the great development of modern military, data link communication is more andmore widely used. The demand of building the aviation data link is now more and morestringent．Therefore, to build steady, reliable and good anti-jamming data linkcommunication system has been a very important factor to improve the battle effectivenessof our air force now. The Technology of information encode is the key technology ofinformation share an deficiency transmission of airborne data link. In order to improve theanti-interference ability of airborne load data chain, to carry out the research on airbornedata link channel coding technology based on the more and more urgentIn this paper, firstly introduces the background and significance of the airborne datalink communication, and the review of research status at home and abroad. According tothe requirements of chain message frame structure of airborne data link, load data linksystem in airborne and channel coding theory, focuses on the key technologies of channelcoding. This paper first analyzes the airborne data link basic principle and system designrequirements, the data chain channel coding and the performance requirements of Turbocodes and decoding algorithm, Turbo coding algorithm for airborne data link is studied. Atthe same time, using VHDL language to implement the baseband hardware description,analysis and verification test focus on the completion of encoder and decoder of Turbocodes, tests showed that the system can meet the basic requirements of the project.
