Rician fading or Ricean fading is a stochastic model for radio propagation anomaly caused by partial cancellation of a radio signal by itself — the signal arrives at the receiver by several different paths (hence exhibiting multipath interference), and at least one of the paths is changing (lengthening or shortening).
The probability density function is (,) = ((+)) (),where I 0 (z) is the modified Bessel function of the first kind with order zero.. In the context of Rician fading, the distribution is often also rewritten using the Shape Parameter =, defined as the ratio of the power contributions by line-of-sight path to the remaining multipaths, and the Scale parameter = +, defined as the total power ...
Examples of fading models for the distribution of the attenuation are: Dispersive fading models, with several echoes, each exposed to different delay, gain and phase shift, often constant. This results in frequency selective fading and inter-symbol interference. The gains may be Rayleigh or Rician distributed.

A Chicago teenager is in a coma and three of his family members are dead after the group was shot at while vacationing in Mexico last week, according to the U.S. State Department and local reports ...
Usually, a factor k is used in the equation above, modified to be k > 1 means geometrically reduced bulge and a longer service range. On the other hand, k < 1 means a shorter service range. Under normal weather conditions, k is usually chosen [5] to be 4 ⁄ 3. That means that the maximum service range increases by 15%.
