Implementation of a Wideband Directional Channel Model for a UMTS Link Level Simulator

This paper deals with the implementation and the assessment of a wideband directional channel model (WDCM) based on the COST 259 recommendations. Cluster of replicas are introduced by means of tapped delay line (TDL). A good compromise between accuracy of the model and complexity required by the simulator is guaranteed by a suitable statistical approach based on deterministic considerations. In the paper a WDCM implementation for a micro cell case is presented, with particular attention to the cluster position and the mobility model concept. Finally, channel model assessment is performed by comparing simulation results in the general street los radio environment with a recent measurement campaign. Proposed channel model can be used in a link level simulator (LLS).
