GEOMETRICALLY BASED POWER AZIMUTH SPECTRUM MODELS FOR MOBILE COMMUNICATION SYSTEMS

摘要

A geometrically base single bounce power azimuth spectrum model for mobile communication systems is proposed in this article. The scatterers are assumed to distribute around the transmitting antenna within a circular region. The distribution of the scatterers can be arbitrary, e.g., Rayleigh, exponential etc. Power azimuth spectrums are derived for these propagation environments. Comparisons between our theoretical calculations and the empirical results as well as the measurement data reported in the literature show that the Rayleigh distribution scatterer models is applicable for the outdoor microcell propagation environment, while the exponential distribution scatterer model is accurate for the indoor office/laboratory propagation environment.
