3-D Modeling and Analysis of Blockage Effects on the Performance of Urban Wireless Communication Systems

Résumé

This paper introduces a 3-D model for wireless communication systems in order to evaluate their performance under hybrid fading assumption for LOS and non-LOS environments. The model is based on the concepts of 3-D stochastic geometry that describes the different cells positions in the network with realistic constraints, and the random shape theory which characterizes the random blockages in urban cellular networks. Here, we assume that the blockages are randomly distributed as a Boolean scheme of rectangles. Based on that, probabilities of line-of-sight (LOS), for 2-D and 3-D models, are evaluated, and the corresponding coverage probability expressions are detailed and derived under the assumption of Rayleigh fading, Rice fading and hybrid fading. Using numerical results, the analytical derived expressions are evaluated, and the advantages of employing the more realistic 3-D model are investigated.
