Abstract
In this paper, the spatial and temporal dispersion and 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 rms delay spread (DS) and rms azimuth spread (AS), respectively, while the correlation properties are determined by the spatio-temporal correlation coefficient. A strong correlation is observed with the presence of the 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. The average values of the rms DS and rms AS for all investigated environments and scenarios are also given. These parameters can be used as empirical values for the 5 GHz band WLAN systems.
