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:

“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)

“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)

“Last night
as if death had lit a pale light
in your flesh, your flesh
was cold to my touch, or not cold
but cool, cooling, as if the last traces
of warmth were still fading in you.”
—Denise Levertov (b. 1923)
