Abstract :
A directional wideband measurement campaign has been performed in urban macrocells at 2 GHz using a channel sounder and a 8-sensor linear antenna array at the base station. Directions of arrival at the base station were estimated by beamforming using the antenna array. Directions of arrival at the mobile were estimated by beamforming using parts of the measurement route. Azimuth-delay power profiles at the base station and mobile are given to show the clustered structure of the propagation channel in urban macrocells environments. This paper also presents a fast and simple method to extract clusters from a large amount of data
