Comparison of One- and Two-dimensional Slow Fading Models in Mobile Radio System Simulations
C. Osterkorn, Gerald Ostermayer, Mario Huemer · 2006
This paper investigates the behavior of two different slow fading models in cellular mobile radio systems. A one-dimensional and a two-dimensional model are compared with respect to their influence on the results of system level simulations for cellular systems. A disadvantage of most known slow fading models is that they cannot handle the correlation behavior of shadowing in two dimensions. Recently a new model, which provides a two-dimensional correlation property, was proposed by Cai and Giannakis (2003). We show that this model gives different results for system capacity and handover rates than the well known one-dimensional models.
