Recently, we evaluated the decoding reliability ... WebThe Rayleigh distribution is a continuous distribution with the probability density function : f (x; sigma) = x * exp (-x 2 /2 σ 2) / σ 2. For sigma parameter σ > 0, and x > 0. The Rayleigh distribution is often used where two orthogonal components have an absolute value, for example, wind velocity and direction may be combined to yield a ...
