Estimation of Spatial Channel Model in a Wireless Ultra-Wide-Area Backhaul Network using the Deterministic Ray Tube Method

This paper presents an analysis of channel characteristics in a wireless ultra-wide-area backhaul network based on deterministic ray tube (DRT) ray tracing. The accurate knowledge of spatial temporal channel characteristics enables system-level simulations of wireless communication systems. However, few papers have been published on the analysis of channel characteristics in an ultra-wide-area backhaul network, which is one of a promising fifth generation (5G) scheme. In this paper, we conduct an analysis of the outdoor propagation environment using the DRT ray tracing. Spatial temporal channel parameters are then calculated using linear regression and multipath clustering algorithm. The proposed analysis scheme is verified by comparing the results of existing scenario with the reference spatial channel model (SCM) parameters. Channel characteristics in the wireless ultra-wide-area backhaul scenarios are then investigated.
