Propagation and Wireless Channel Modeling Development on Wide-Sense Vehicle-to-X Communications

Abstract

The need for improving the safety and the efficiency of transportation systems has become of extreme importance. In this regard, the concept of vehicle-to-X (V2X) communication has been introduced with the purpose of providing wireless communication technology in vehicular networks. Not like the traditional views, the wide-sense V2X (WSV2X) communications in this paper are defined by including not only vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) communications but also train-to-X (T2X) communications constituted of train-to-train (T2T) and train-to-infrastructure (T2I) communications. All the information related to the wide-sense V2X channels, such as the standardization, scenarios, characters, and modeling philosophies, is organized and summarized to form the comprehensive understanding of the development of the WSV2X channels.

On MIMO Channel Modeling for the Mobile Wireless Systems

“…As a consequence, the performance of the majority of deterministic channel simulators can only be improved by increasing the number of sinusoids. The deterministic modeling method can be more suitable if the network planning or system level simulation has highly accurate requirements [12]. Examples of deterministic models are Ray Tracing and Stored Measurement Data [8].…”

“…Indeed, as long as the wavelength is small compared to the dimensions of obstacles [11]. W. Jiang and K. Guan, [12], 2013, illustrates that the deterministic channel models based on Ray-tracing techniques, model the propagation channel using the geographical information from the database. The diffuse scattering is also taken into account on the surfaces seen by both the transmitter and receiver.…”

Evaluation of Road User Radio-Frequency Exposure Levels in an Urban Environment From Vehicular Antennas and the Infrastructure in ITS-G5 5.9 GHz Communication

“…Among the many technologies embedded in the ITS, Vehicle-to-Everything (V2X) communication is the backbone for connected and autonomous vehicles on the road, creating a wireless network where vehicles, infrastructures, and pedestrians exchange information. These technologies are specifically referred to Vehicle-to-Vehicle (V2V), Vehicle-to-Infrastructure (V2I), Vehicle-to-Pedestrian (V2P) and Vehicle-to-Network (V2N) communication [3]- [6]. More precisely, V2V provides the communication between vehicles through On-Board Units (OBUs), i.e., installations within the vehicle designed for information transmission; V2I provides the exchange of information with infrastructural Roadside Units (RSUs), and V2P involves communication with electric devices owned by the road user such as smartphones or generic wearables devices.…”
