Method-of-moments parameter estimation for compound fading processes

A novel and general parameterized fading model for the instantaneous received path power is presented, which accounts for both wide-sense stationary shadowing and small-scale fading. A method-of-moments parameter estimator is derived and implemented using a non-linear least-squares algorithm. Performance is explored by analysis and simulation under different noisy channel scenarios, and compared to exact Cramer-Rao bounds in the case of uncorrelated shadowing, and to idealized CR bounds, where shadowing and small-scale fading processes are assumed to be observed separately, in the case when shadowing correlation was not negligible.
