Summary:
In this contribution, the cross-correlation of the fadings in two propagation channels is studied. It is shown that the behavior of the large-scale fading cross-correlation is determined by the joint spread function (JSF) of the two channels, which describes the correlated behavior of the dispersion of two channels in the parameter space in small-scale. Two parameters are proposed to characterize the JSF which are respectively the maximum of the absolute JSF and the mean of the JSF. Simulations are conducted using a propagation-graph modeling method to investigate the variation of these parameters with respect to the geometry of the environment. The results obtained are valuable for constructing stochastic models for multi-link propagation channels in cooperative relay scenarios.
