Abstract :
In this paper, the short-term time variation of wideband channels is investigated based on some extensions to the WINNER interim beyond-3G (IB3G) spatial channel model (SCM), using the full channel correlation matrix. These extensions mainly include some modifications of the generation of the wideband fast fading channel matrix, such as the consideration of the time variant sub-path phases at the mobile station (MS), and of the time variant path powers, and the generation of different last bounce distances (LBDs) for the mid-paths within each path. In order to measure the short-term time variation of the wideband channels, this paper presents a redefinition of the correlation matrix distance (CMD) metric, which was originally proposed for the narrowband fast fading scenario. By comparing the simulated CMD generated from the newly extended 3GPP (NE-3GPP) SCM with that of the measurements taken in the FLOWS project, we find the following main conclusions: (1) The Kronecker assumption can not be applied in calculating the instantaneous full channel correlation matrix, since it leads to significant deficiencies in the simulated CMDs from the NE-3GPP SCM. (2) The simulated CMDs generated from the NE-3GPP SCM compares better to the measurements taken in the FLOWS project than that of the IB3G SCM
