A wideband HF interference and noise model based on measured data

Describes the first results of a high-resolution, wide-bandwidth North American HF band interference measurements program in terms of the correspondence of these results with a model for the interference derived from earlier European measurements. The preliminary conclusion is that the model is valid. The interference-dominated portion of the frequency distribution is approximately linear on a log-log plot which relates the fraction of the resolution cells occupied with interference at a power level to that power level.<
