Analysis of fading statistics based on angle of arrival measurements

In this paper, we analyze various spatial channel measurements using their second order statistics like level crossing rate, average fade duration, auto covariance and coherence distance. Occurrence rates of the angle of arrival in considering macro, micro and Pico cellular environment are used for the analysis. Effect of directional antennas employed at the base station and mobile station on second order statistics is also analyzed. We also present the quantative analysis of the measurements using multipath shape factors i.e. angle spread, the angular constriction and direction of maximum fading. Effect of increasing Doppler spread on the LCR and AFD is also elaborated in detail.
