Abstract :
In this paper, we propose two extensions to a propagation model generating time-series of large-scale power variations caused by vehicular scattering in small-cells. Those extensions bring fading correlations between multi-links by exploiting either mobility simulation results or geometric characteristics of radio links. The model and its extensions are evaluated against a full-deterministic model in the configuration of a LTE network deployment. First-order statistics of the model are validated. Multi-link inter-correlation properties are proven to be well reproduced by the proposed extension. Finally, the computation time is shown to be divided by a factor of 20 to 40 relative to the full-deterministic model.
