Abstract

In this letter we derive an explicit model for the cross- correlation function of the shadowing components affecting the links between a mobile station and two base stations. This model in- cludes both the autocorrelation model proposed in earlier work by Gudmenson in 1991 for the single component, and the cross-corre- lation early evidenced in the work by Graziano in 1978. The model is useful in analytical computations, e.g., of second order statis- tics of signal-to-interference ratio. The model can include the be- havior of a time-variant cross-correlation at zero-time shift and of a non-homogeneous environment.
