An adaptive HF system and its computerized performance evaluation

Presents the principal requirements from a modern adaptive HF communication system, the basic design concepts of the implemented system which successfully answers these requirements, the accompanying field trial methodology and briefly, some of the field trials results. The basic lesson learned from the implementation and the field trials of the described system is that a modern HF communication system can fulfil the current and future requirements of C3I systems only if it glues together a number of technical features including self-healing architecture, automatic digital operation, real time, adaptive frequency management, HF oriented error detection and correction codes and communication protocols. ALE, LQA and simple and efficient man-machine interfaces. A mandatory phase is developing such systems is the field trials which should be performed with computer aid, using appropriate methodology and tools.<>
