Advanced HF ant-jam network architecture

The Hughes HF2000 system was developed for military communications using a flexible architecture which utilizes a wideband RF front-end and extensive digital signal processing. The HF2000 antijamming (AJ) mode was field tested via an HF skywave path between Fullerton, CA and Carlsbad, CA ( approximately 100 miles), and it was shown that reliable fast frequency-hopping data transmission is feasible at 2400 bit/s without adaptive equalization. The necessary requirements of an HF communication network are discussed, and how the HF2000 AJ mode can be used to support those requirements is shown. The Hughes HF2000 AJ mode system architecture is presented.<
