Abstract :
Knowledge of the statistics of the angle of arrival can be used as the basis of a model for the simulation of impulse response functions of the indoor radio propagation channel over small spatial separations. Results of an analysis of the angle of arrival distribution for an extensive database of indoor radio propagation measurements are presented. Multiple Signal Identification and Classification (MUSIC) is used to estimate the angle of arrival of sub-components within the resolved multipath components of the measured impulse response functions. Distributions for the number of and angle of arrival of these sub-components are presented for varying excess delays
