Descriptive fade slope statistics on INTELSAT Ku-band communication link

Descriptive statistics of fade slope from the INTELSAT VI beacon data at 11 .198GHz and 42.8 degrees elevation are presented. Results indicate a direct positive correlation between the mean values of fade slope and attenuation and show that individual rain events have higher fade slope with deeper fa de depths. The absolute fade slopes can be best approximated by a log-norma l distribution. Positive and negative fade slopes are symmetrically distrib uted and the distribution becomes flatter at higher attenuation levels.
