Channel Characterization
A Rician fading channel can be described by two parameters: and . is the ratio between the power in the direct path and the power in the other, scattered, paths. is the total power from both paths, and acts as a scaling factor to the distribution.
The received signal amplitude (not the received signal power) is then Rice distributed with parameters and . The resulting PDF then is:
where is the 0th order modified Bessel function of the first kind.

Famous quotes containing the word channel:
“The Xanthus or Scamander is not a mere dry channel and bed of a mountain torrent, but fed by the ever-flowing springs of fame ... and I trust that I may be allowed to associate our muddy but much abused Concord River with the most famous in history.”
—Henry David Thoreau (18171862)
