Abstract

An important parameter in characterizing radio communications channels is the coherence bandwidth. This paper presents an analysis of the coherence bandwidth in a urban microcell environment where the dynamic channel response is determined by a site-specific ray-tracing propagation model. Such an analytical model provides a direct calculation of signal fading envelope correlation as a function of frequency and location. The analysis here shows that coherence bandwidth is strongly dependent on location within a particular propagation environment and only weakly related to RMS delay spread. Typical results for frequency diversity gain for various frequency separations are also presented
