Advanced HF digital networks

The authors introduce technology enhancements in HF communications that have been developed by Rome Laboratory (RL). Titled 'Improved HF Data Network' (IHFDN), the technology improvements for this effort addressed networking for a large mobile network of up to 100 users contained in up to 10 nets having a totally distributed architecture. Specifically, improvements covered are in HF networking, LQA (link quality analysis) techniques, LPD/LPE (low probability of detection/low probability of exploitation) waveforms for operational security, and frequency-hop frequency management. This Phase I effort has made available a PC portable simulation with design, user, and programmer manuals, and a final report with an appendix covering the cooperative work done between RL and others.<
