Abstract
The statistics of direction of arrival (DOA) in an urban environment are generated based on measurement and ray tracing simulation. The angular power distributions at different locations of the city are fit into the Gaussian angle‐of‐arrival model. The following four quantities are then extracted as model parameters: The number of incoming DOA, the normalized amplitude of each incoming signal, the mean direction of the incoming signals, and the standard deviation of the incoming signals about the mean direction. It is shown that the statistics of the above four quantities resulting from the simulation are in good agreement with those from the measurement data. © 2002 Wiley Periodicals, Inc.
