Design And Implementation Of HF Auto Selectable Communication System Software

Based on the existing HF communication equipment, the link layer protocols of HF auto selectable frequency communication system are analyzed, and system software possessed frequency automatic selection and data transmission and other communications functions has been designed and realized.The HF communication’s features and HF adaptive technique are introduced in this thesis and application software of the frame structure of system is designed based on the analysis of the data link layer protocols. Then the realizing plan of the automatic link establishment protocol and data transmission protocol are analyzed, which are used in HF automatic frequency selection communication system. The above two software protocol modules established on Visual C++6.0platform are emphasis in this thesis. After integrating the serial port connection module and other functional module, the complete application software of this system possessed frequency automatic selection and data transmission and other communications functions is constituted.Finally, the testing experiment of the software of this system is presented, the test result shows the feasibility of this software.
