ALE In HF Communication System

High-frequency communication is a traditional communication technology, because of its simple equipment, easy to use, the advantages of flexible widely used. But its limited frequency resource, vulnerable to interference and other shortcomings seriously restricted its development.Modern high-frequency communication uses Link Quality Analysis (LQA) technology to obtain channel parameters real-time by scaning all available channels for Automatic Link Establishment (ALE) and communications automation, and to provide the best communication quality. China according to MIL-STD-188-141A made GJB 2077-94 high-frequency adaptive communication system Automatic Link Establishment protocol, belongs to the second-generation HF Automatic Link Establishment.This paper describes a high-performance processor STM32F103RC6 and real-time operating systemμC/OS-Ⅱbased to realize 2G-ALE, the application is user-friendly by graphical user interfaceμC/GUI.
