Abstract :
In this contribution, we derive a distribution that is suitable for characterizing biazimuth (azimuth of arrival and azimuth of departure) and delay dispersion of individual path components in the response of the radio channel. This distribution maximizes the entropy under the constraint that its first and second moments are specified. We propose to use the density function of the derived distribution to characterize the shape of the biazimuth-delay power spectrum of individual path components. The applicability of this characterization in real conditions is assessed using measurement data.
