An Optimal Lognormal Approximation to Lognormal Sum Distributions

IEEE Transactions on Vehicular Technology, 2004
Sums of lognormal random variables occur in many problems in wireless communications because signal shadowing is well modeled by the lognormal distribution. The lognormal sum distribution is not known in the closed form and is difficult to compute numerically.
