fading margin

[′fād·iŋ ‚mär·jən]

Number of decibels of attenuation which may be added to a specified radio-frequency propagation path before the signal-to-noise ratio of a specified channel falls below a specified minimum in order to avoid fading.
Allowance made in radio system planning to accommodate estimated fading.
