Fading
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:
“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)
“This is the dead land
This is cactus land
Here the stone images
Are raised, here they receive
The supplication of a dead man’s hand
Under the twinkle of a fading star.”
—T.S. (Thomas Stearns)
“Opinion is not worth a rush;
In this altar-piece the knight,
Who grips his long spear so to push
That dragon through the fading light,
Loved the lady; and it’s plain
The half-dead dragon was her thought....”
—William Butler Yeats (1865–1939)
