Abstract :
In this paper, shadow fading (SF) in an indoor multipath environment is measured and the spatial correlation of SF is modeled statistically. To effectively extract SF from the measured field strength, we use frequency averaging (FA) method instead of spatial averaging (SA) method which has generally been used. SF is modeled as a random variable with a log-normal distribution. The spatial correlation model for SF is expressed by an exponential decay function with convergence to non-zero value.
