Multipath propagation in line-of-sight links
Electronics Letters, 1979 Using a classical model, and adding two complementary propositions, it is possible to obtain a general method for calculating the fading distribution laws on line-of-sight links of indifferent lengths undergoing multipath propagation. In particular, it is shown that the conventional empirical d3.5 power law gives a rough approximation in a very limited
