Abstract: A hypothetical aircraft-to-ground communication channel is examined for frequencies in the 2 -30 MHz band, and in the 200 -400 band. The channel is characterized by its correlation function and scatter function. Particular attention is given to the effects of multipath spread and frequency spread on the performance of a non-coherent, frequency-shiftkeyed, matched filter receiver. If the channel multipath spread is appreciable then the probability-of-error vs signal-to-noise ratio curve has a minimum beyond which increases in signal-to-noise will not decrease probability-of-error.
