Abstract : Propagation management in the HF/VHF spectrum is very complex for adaptive skywave communications system. Understanding and readily coping with these complexities is part of an ongoing independent research and development project within Collins Defense Communications. This paper will describe the development of a propagation management system, the various resources used, and how expert systems are being applied. The latter will include the kind of rules developed and the types of expert systems explored. Because products developed are to support mobile/portable radio systems, PC-based expert systems will be used for implementation.
