In wireless communications, fading is deviation of the attenuation affecting a signal over certain propagation media. The fading may vary with time, geographical position or radio frequency, and is often modeled as a random process. A fading channel is a communication channel comprising fading. In wireless systems, fading may either be due to multipath propagation, referred to as multipath induced fading, or due to shadowing from obstacles affecting the wave propagation, sometimes referred to as shadow fading.

Famous quotes containing the word fading:
“a little sight left in the corner
Of one eye fading seeing something wave lies believing
That she could have made it”
—James Dickey (b. 1923)
“His golden locks time hath to silver turned;
O time too swift, O swiftness never ceasing!
His youth ‘gainst time and age hath ever spurned,
But spurned in vain; youth waneth by increasing.
Beauty, strength, youth are flowers but fading seen;
Duty, faith, love are roots, and ever green.”
—George Peele (1559–1596)
“Devouring Time, blunt thou the lion’s paws,
And make the earth devour her own sweet brood;
Pluck the keen teeth from the fierce tiger’s jaws,
And burn the long-liv’d phoenix in her blood;
Make glad and sorry seasons as thou fleet’st,
And do what’er thou wilt, swift-footed Time,
To the wide world and all her fading sweets;”
—William Shakespeare (1564–1616)
