A vector has two components, which are normally distributed with the same nonzero mean

and the same variance

. Assuming

and

, find the distribution of the length of the vector:
In the theory of fading channels,
RiceDistribution is used to model fading amplitude in the situation when the signal is composed of one strong direct line of sight and many weaker random components. Find the distribution of instantaneous signal-to-noise ratio where

,

is the energy per symbol, and

is the spectral density of white noise:
