Channel Simulation and Validation by QuaDRiGa for Suburban Microcells under 6 GHz

Abstract

3GPP (3rd Generation Partnership Project) recommends QuaDRiGa (Quasi-Deterministic Radio Channel Generator) as the 5G preferred simulation platform. In this work, based on experimental measurements performed at 2.55 GHz for both LOS and NLOS scenarios, channel parameters like delay spread (DS), angle spread (AS) are analyzed. Furthermore, based on QuaDRiGa simulation platform, the accuracy of channel parameters like azimuth spread of arrival (ASA), elevation spread of arrival (ESA), azimuth spread of departure (ASD) are validated. The 3D features of received powers are illustrated. Results of QuaDRiGa simulation match quite well with experimental measurement data. This indicates that QuaDRiGa platform can be used for design and simulation of 5G wireless communications systems.
