Abstract :
Frequency-shift, phase-shift, and on-off amplitude modulation are examined as mechanisms. Curves of fractional error as a function of average carrier-to-noise ratio are derived for fading and non-fading carriers. The results are applicable to telegraph, teletype, and other binary-coded signals.
