NPS NRP Executive Summary In this feasibility study, we propose the application of advanced waveforms techniques (e.g. Orthogonal Frequency Division Multiplexing, OFDM) for high data rate HF communications within the Battle Force Tactical Network (BFTN). OFDM and other multicarrier-type modulations can potentially mitigate the multipath problem that HF is subjected to and potentially increase the limited data throughput of HF systems. While SATCOM provides reliable RF communications and data links, the Navy needs a viable alternative to SATCOM. Beyond line of sight (BLOS) HF communications (2-30 MHz band) can be improved using advanced digital waveform techniques that are used in wireless and cellular communications. It can be a complementary system or be the solution to SATCOM-degraded scenarios.
