Direction-of-arrival of partial waves in wideband mobile radio channels for intelligent antenna concepts

A method for wideband measurement and for post-processing of mobile radio channel impulse responses which include unambiguous information about the directions-of-arrival in the azimuth is introduced. Based on this method, measurement results for outdoor macrocellular environments are presented. These results are essential for assessing, developing, evaluating and optimizing adaptive directional antenna concepts for future mobile radio systems and for extending conventional statistical wideband models of the mobile radio channel to take into account the directions-of-arrival.
