Abstract: Atmospheric radio-noise samples were recorded near Boulder, Colorado, and analyzed to obtain amplitude and time statistics of MF and HF noise. Amplitude and time statistics derived from the Hall model were com­pared with the corresponding measured statistics for atmospheric noise. The measured distributions of noise samples used in previous error-rate tests were compared with distributions derived from the Hall model and from standard atmospheric radio-noise distributions. Performance curves were computed for a CPSK system and for an optimum receiver operating under the same conditions. Atmospheric radio-noise predictions for 20 CONUS locations were furnished.
