Abstract / Description of output
The spatial and temporal correlation properties of a wideband dynamic directional indoor channel at 5.2 GHz are presented based on extensive measurement campaigns in four different environments under various propagation scenarios. Channel spatio-temporal dispersions are assessed in terms of the root mean square (RMS) delay spread and RMS azimuth spread, respectively. A strong correlation is observed with the presence of a line-of-sight (LOS) path, but degraded when the LOS is obstructed. The variations of the spatio-temporal dispersions with mobility are also investigated, where higher values of spatio-temporal dispersions were found when the transmitter and receiver separation increased, particularly in a more cluttered environment.
