| Summary: | 碩士 === 國防大學理工學院 === 電子工程碩士班 === 105 === With the great development of modern military technology, tactical data link is used more and more widely. At present, the development of data link is the most outstanding in the United States, especially Link-16 and Joint Tactical Information Distribution System (JTIDS) are systems of communication, navigation and identification. It can provide high capacity, anti-interference, digital data, and secure voice communications, navigation and information of identification for each platform.
JTIDS is a tactical data link which is used now. It is applied in accordance with associated protocol by the automatic transmit message of the battlefield situation, intelligence, command and control order processing among sensors, command and control information platforms and weapons platforms. Meanwhile, it is also a technical basis on the military electronic message systems, network links and an exchange of information interoperability in the tri-military services.
In this thesis, we explore how to simulate radio signal for JTIDS. Firstly, analyze the characteristics of JTIDS system, message type, transmission packet composition and radio signal generation. Then, we use the Simulink to simulate radio signal for JTIDS. According to the packet structure, we use the Cyclic Redundancy Check (CRC), The Reed-Solomon Code (RS Code), the Interleaving Code, the Cyclic Code Shift Keying (CCSK) and the encryption step by step. The aim is to realize the simulation of the radio signal, so as to facilitate the study of the JTIDS related topics.
