Abstract
A HF RADIO ARCHITECTURE EXISTS THAT WILL SIGNIFICANTLY AID THE NAVY PERFORMING MAJOR UPGRADES TO THEIR OVERALL COMMUNICATIONS NETWORK AND REDUCE THE NUMBER OF DIFFERENT TYPE HF RADIOS PRESENTLY DEPLOYED. THE ARCHITECTURE IS BASED ON THE APPLICATION OF I AND Q BANDWIDTH SAMPLING, DIGITAL IMPLEMENTATION OF FREQUENCY TRANSLATION, FILTERING, MODULATION AND DEMODULATION AND BASEBAND SIGNAL PROCESSING TECHIQUES. ADDITIONALLY, THE ARCHITECTURE IS SOFTWARE RECONFIGURABLE TO MEET ALL HF APPLICATIONS. IN PARTICULAR, THE PERFORMANCE ACHIEVABLE USING DIGITAL FILTERING AND SIGNAL PROCESSING TECHNIQUES FAR EXCEED THAT OF ITS ANALOG COUNTERPART. BITE AND ILS OPPORTUNITIES ARE ALSO SIGNIFICANT DUE TO THE PRIMARILY DIGITAL IMPLEMENTATION AND MODULARITY. A MULTI-INCREMENT TUNING SCHEME IS INCORPORATED WHOSE FINAL STAGE (FINE TUNING 10 HZ STEPS IS IMPLEMENTED DIGITALLY. DUE TO THE UNIQUE CHARACTERISTICS OF EACH USERS INTERFACE, A PROGRAMMABLE INTERFACE PROCESSOR IS INCLUDED TO HANDLE CLOCK RATE CHANGES, FORMAT CONTROL, INTERFACE PROTOCOL AND DATA BUFFERING UNDER SOFTWARE CONTROL.
