Abstract :
The combined spatial-polarization correlation function for indoor multipath environments is discussed. An analytical model based on an isotropic receiving antenna and a sphere of scatterers is developed for quantifying signal decorrelation as a function of antennas´ spatial and orientation separation. A closed form expression is deduced for the combined spatial-polarization correlation function which is useful for quantifying the potential diversity gain in antenna diversity systems. Finally, an extensive set of measurements were carried out at 1947.5 MHz to verify the theoretical results.
