Detailed Description

Uniform delay profile.

With a given maximal delay $\tau_{max}$ the probability density function of the delay is

\[ f(x) = \left\{ \begin{array}{cl} 0 & \mbox{for } x<0, x>\tau_{max} \\ \frac{1}{\tau_{max}} & \mbox{for }0\le x\le \tau_{max} \end{array} \right. \]

Though this is not liked by the communication engineers, it is nevertheless interesting from an information theoretic viewpoint because for any random variable with limited value range, the uniform distribution is the distribution with maximum entropy.
