The Design And Implementation Of Software-hardware Platform And Fh Synchronization Of Soldier Radio Station

Possessing the strong ability of anti jamming, anti-fading, anti-interception as well as the application of multiple access, Frequency hopping(FH) communication is widely used in the modern military communication, especially in the tactical anti jamming radio with the purpose of ensuring the modern army to build certain reliable data and voice communication under some adverse electromagnetic surroudings. Synchronization is the key of FH communication, which can convey information and exert the advantage of FH communication only after the realization of high-speed, accurate synchronization. Meanwhile, synchroniz ation is also the difficulty of the development of FH system, which needs supplicated design especially in the fast frequency hopping (FFH).At present the microelectronic technology swift and violent development, the processor rate of rise also sped up along with it, embeded system domain to have the earth-shaking change, it to become the research hot spot, it's characteristic conforms to the modern military message center attention to cooperation performance, repeatable programming, and system open performance and so on many requests. The main work of this paper is realizing a high-speed fxequency hopping station adapting to new military requisition by embeded system.After the introduction of FH communication's principle, Based on the main requests of synchronization for a high-speed FH communication system, this paper puts forward a synchronization scheme of a high-speed FH system, which is achieved by usingmethod combined synchronization-head with time of day (TOD). This paper describes hardware platform in a detail way, and it is a embeded system that core of ARM. Software platform adopts embedded Linux, and it set up across-edit circumstance. Last summarized and expectated the paper.
