Statistical Analysis of the Multiple Scattering Radio Channel

The concept of multiple scattering radio propagation channels-in contrast to the conventional single (Rayleigh) scattering-has been proposed and found to be a fitting model in certain propagation scenarios. Except for some special cases, expressions for the amplitude distribution of such channels are unknown. In this paper, we derive distribution functions for the amplitude of the general multiple scattering radio channel. Rice, Rayleigh, and double-Rayleigh distributions are special cases of the general result. We also derive a computationally simple moment-based estimator for the parameters of the distribution. In addition to the measurement analysis of multiple scattering propagation channels, our results can also be applied in the performance evaluation of communication schemes over such media
