Abstract
An integral aspect of radio propagation especially outside of buildings is the loss due to shadow fading (also known as long-term fading). This is caused by the presence of obstacles which lie in the propagation path of the radio waves. While modeling the shadow fading loss, the spatial, angular and temporal correlation of the shadow fading values has to be considered. By that, it is taken into account that an obstacle which lied in the propagation path during the last measurement of the radio wave cannot simply disappear at the following measurement. Moreover, signals coming from the same direction experience a similar shadow effect and the location dependency of the shadow fading values makes sure that another mobile at the same location also gets the same signal attenuation.
This article aims at generating shadow fading profiles which can be used in simulations of realistic mobile radio network scenarios. The focus is on achieving two-dimensional spatial correlation of the shadow fading values. Methods for introducing the angular and temporal correlation are explained in addition. Simulations with the different shadow fading profiles are run and comparisons between quality-of-service (QoS) aspects obtained with these profiles are presented.
