Average fade / nonfade duration is inversely proportional to Doppler spread

Fade durations rapidly reduce with increasing margin, but time between fades increases much slower

Experiments say that for large fade margins: fade durations are exponentially distributed.

Average fade duration

• Rayleigh-fading channel
• versus fade margin
• for n = 1, 2, 3, 4, 5 and 6 Rayleigh-fading interfering signals.
• Normalized by dividing by the Doppler Spread.
