Software Research And Implementation Of3G-Ale Shortwave Data Transmission Radio

Short wave communication as a long distance communication approach has long been used by humans.Because of the far transmission distance, network convenience,low costs and easy to repair and other advantages, shortwave communication is still used extensively. In recent years, with the rapid development of science and technology, people demand higher improvement for shortwave communication. In1999,the U.S. military protocol MIL-STD-188-141B has defined the technology requiremens of third generation short-wave communication. However, the research in this field in China is relatively late. In2007, Chinese PLA General Armament Department issued the short wave adaptive communication system protocols for automatic link establishment(GJB2077A-2007). On the base of the study of national military standard, the paper focuses on software design and implementation of3G-ALE shortwave data transmission radio’s high speed data transmission service in the Linux system simulation platform and embedded ARM board using C language and MiniGUI. First of all, the paper reviews the history of the shortware,3G-ALE protocol and MiniGUI, and explain the study of the significance and the characteristics. And then the paper describes the selection of software and hardware platform and explains the reasons for the selection. Then the paper introduces3G-ALE protocol framework and key technology, and study the data link layer’s and physical layer’s important technology. Finally,based on GJB2077A-2007,the paper introduces the independent design of shortwave data tansmission radio system’s overall design and respectively discusses the physical layer’s, data link layer’s and application layer’s software design and implementation,and realizes a set of test demonstration system. From the demonstration system of the testing results, the radio system has basically realized shortwave data tansmission radio’s call and data transmission business process and realized the data updating function between the fixed link two radioes. At the end of the paper summarizes this research and at the same time proposes future prospects.
