Terrain and Clutter Impact on Joint Statistical Properties of Azimuth Spread and Delay Spread in Macro-cell Bad Urban Environment

Abstract

In this paper a realistic directional channel model that is an extension of COST 273 channel model is presented. The model uses a previously developed cluster and visibility generation strategy with increased realism, due to the introduction of terrain and clutter information. The new model was implemented using terrain, clutter, street and user mobility information for the city of Lisbon,Portugal. The simulation analysis was performed and joint statistical properties of azimuth spread and delay spread were compared with other models and available experimental data. The introduction of clutter and terrain information into the simulations produces an increase on multi-path delay and azimuth spread, underlining Lisbon bad urban characteristics.
