HF Interference, Procedures and Tools (Interferences HF, procedures et outils)
Abstract
This Report presents the results of the work carried out by IST-050/RTG-022 the Research Task Group (RTG) on "HF Interference Procedures and Tools" to address the concerns raised by the potential for unintentional radio interference to be caused by the widespread operation of broadband wire-line telecommunications systems, such as PowerLine TeleCommunications (PLT, PLC) and various forms of Digital Subscriber Line (xDSL). Increase of the existing HF noise floor by widespread use of PLT and/or xDSL will bring up problems for Military Radio Users as well as for HF Communication Intelligence (COMINT) in all NATO countries The signal-to-noise ratio thus may be reduced for tactical and strategic HF radio as well as for fixed sensitive COMINT sites. Each Chapter of the Report addresses specific topics, namely, introduction, HF radio, characteristics of PLT and xDSL systems, emission limits, measurement methods, propagation models, FMC modelling, and FMC analysis, culminating in conclusions and recommendations The Report also provides a comprehensive list of references and a software tool (electronically available) Briefly, the findings of the RTG do indicate that the PLT emissions have the potential to cause appreciable degradation in the exploitation of the HF spectrum by military users
