Abstract

This paper presents dynamic radio channel measurement using a fast wideband complex radio channel sounder and an antenna array. Examples of continuous channels of a moving mobile are presented. The array reception allows the investigation of channel dispersion in both angle and time. In addition, wideband measurement gives information of the coherence bandwidth of the 2D channel, essential for downlink beamforming in FDD systems. Also correlation between the elements in the array is studied
