“…The authors in [28] proposed to carry out virtual drive testing (VDT), by reproducing RTsimulated channels by means of the field synthesis technology. The results generated from RT simulations of interior scenes for a penetrable hollow wedge formed by multilevel walls can correspond to that of the 3D full wave [29]. [30] presented many kinds of methods for direct optimization with regard to point-to-point ionospheric RT.…”

To realize reliable and stable millimeter-wave (mmWave) vehicular wireless communication, the research of vehicular channel characteristics in the dense urban environment is becoming increasingly important. A comprehensive research on the channel characteristics for 30 GHz vehicular communication in the Beijing Central Business District (CBD) scenario is conducted in this paper. The self-developed high-performance ray-tracing (RT) simulator is employed to support intensive simulations. Based on simulation results, the effects of multiantenna and beam switching on the key channel parameters are analyzed, as well as the impact of different traffic flows. The results can provide theoretical and data support for the evaluation of vehicular channel characteristics and will help for the design of the vehicular communication system enabling future intelligent transportation.

“…Hence, the combination of millimeter-wave and MIMO technology has become a research hotspot in 5G communications. MIMO channel propagation at high frequency can be predicted by the Shooting and Bouncing Ray/Image (SBR/Image) method in a complex environment, which is modified based on the ray-tracing method [3].…”

The combination of millimeter-wave and MIMO channel is a hotspot in the research of fifth-generation (5G) communication in recent years. In this paper, the SBR method is used to simulate a typical indoor office environment in the line-ofsight (LoS) scenario and the near-field scenario. The frequency is 28 GHz, and the receiver is an 8*8 vertical planar array. Firstly, the effectiveness of the SBR method is verified by analyzing the power angle profiles (PAPs) of the azimuth angle of arrival (AAoA). Secondly, the spatial non-stationary characteristics of the millimeter-wave MIMO channel are analyzed through the received power and power delay distribution of elements at the antenna's array. Some characteristics of the millimeter-wave MIMO channel are revealed from these analyses.
