Data Link Layer Design And Implementation In VHF Radio Communication System

With the high development of electronic technology, the modern high-tech battlefield gradually tends to digitalization and network. Command and communication system sharp increase in the amount of information transmission, transfer more and more types of business. In the 21st century digitized battlefield required to achieve seamless communications, high-speed data transfer to complete a comprehensive business and hope there is broadband data transmission equipment that the broadband data the composition of non-tactical radio backbone network, through the Internet protocols for information sharing between the various units. We have adopted a software-defined radio and structure of FPGA+DSP-based hardware platform, using high-speed frequency hopping, error correction coding anti-interference measures, designed and implemented an ultra-short wave radio communication systems. The solution could be a good communication system standards greatly reduce the communication system development time and cost.The author involved in the data link layer of the system design and implementation and system testing. The design of the data link layer uses a lot of relevant theory to ensure the satisfaction of design requirements. This paper discusses the system released point-to-point communication, link building, data communication, the synchronization's control of the design and implementation. This paper also describes the system used in some of the other technologies. Finally, a large number of test results show that our products meet the design requirements.
