Characterization of second order moments of a Multi-Cluster Gaussian Scatterer Distribution channel model

This document presents the analysis of second order moments of a Multi-Cluster Gaussian Scatterer Distribution channel model. This analysis involves the evaluation of the marginal probability density functions for both the Angle of Arrival and Time of Arrival of scattered signals. Using evaluation and computer simulation it is shown that adequate modelling of a multi-cluster environment is necessary in order to assess the advantages of using multi-antenna technologies. The Angle Spread is used as a second order moment statistic to determine the channel behaviour in relation with model variations. Closed form expressions both original and from other works are used to model the channel.
