Deterministic and stochastic channel models implemented in a physical layer simulator for Car-to-X communications

Abstract

Abstract. This paper presents a physical (PHY) layer simulator of the IEEE 802.11p standard for Wireless Access in Vehicular Environments (WAVE). This simulator allows the emulation of data transmission via different radio channels as well as the analysis of the resulting system behavior. The PHY layer simulator is part of an integrated simulation platform including a traffic model to generate realistic mobility of vehicles and a 3D ray-optical model to calculate the multipath propagation channel between transmitter and receiver. Besides deterministic channel modeling by means of ray-optical modeling, the simulator can also be used with stochastic channel models of typical vehicular scenarios. With the aid of this PHY layer simulator and the integrated channel models, the resulting performance of the system in terms of bit and packet error rates of different receiver designs can be analyzed in order to achieve a robust data transmission.

Impact of buildings on vehicle-to-vehicle communication at urban intersections

“…The dynamic and complex topology of VANETS and the inevitable presence of numerous mobile and static obstacles such as buildings, vegetation and other vehicles, especially frequent at urban intersections, pose a challenging problem. Although effects influencing radio wave propagation have been well investigated [9], [10], [11], a validated and representative 5.9 GHz non-line-of-sight (NLOS) path-loss model for vehicular urban environment is still missing [12], [13], [14], [15], [16]. This is primarily due to the complexity of developing theoretical models which required the use of a large number of equations describing the physical structure of radio wave propagation.…”

On the Feasibility of High Speed Railway mmWave Channels in Tunnel Scenario

“…Moreover, for investigating the detailed channel characteristics in such high-dynamic scenario, a well-studied RT time-interpolation algorithm is employed to expose the channel small-scale characteristics. The RT, in this study, is developed based on ray-optical algorithm [20] at Technische Universität Braunschweig [21]. It is three-dimension (3D) channel simulator which is performed in 3D digital map.…”
