Abstract
The HF channel is characterized with regard to frequency
selective fading and atmospheric noise under restrictive
mathematical assumptions, and compared with measured
statistics. Actual channel characteristics are utilized to
obtain parameters for choosing appropriate convolutional
codes. Short threshold decodable convolutional codes with
only a moderate amount of interleaving are shown to be
capable of affecting a reduction in the output error
probability by at least an order of magnitude, for uncoded
error probabilities on the order of 2 x 10ˉ².
