WebWhen all the X are independent identically distributed 2-Erlang random variables. It follows that the exact distribution of the sum is a 2 N-Erlang distribution, but as N is likely to be large, this can be well approximated as having a Gaussian distribution with mean 9 N and variance Nvar (X ). WebThe latter takes into account the local slopes and shadowing. The second-order Rayleigh–Rice theory is used to express the local electric field on the rough surface and the obtained expressions are then used in the scalar diffraction theory instead of the expressions corresponding to a smooth surface.
