Abstract:
Values of required signal-to-noise ratios are estimated for the following HF communication systems: amplitude-modulation (AM) voice communications systems, noncoherent frequency-shift-keying (NCFSK) radioteletypewriter systems, composite voice and teletypewriter systems, aural-reception radiotelegraphy, and phototelegraphy (facsimile). Except for NCFSK systems, for which certain aspects of the basic performance had to be evaluated in the course of this study, values of required signal-to-noise ratios are estimated from published data in the open literature.
Keywords: fading; frequency shift keying (FSK); amplitude modulation; diversity reception; HF comnunication system; radiotele-typewriter; required signal-to-noise ratio; voice communication; signal theory
