F-802.11P: A Fuzzy Enhancement for IEEE 802.11P in Vehicle-to-Everything Communications

IEEE 802.11p for Vehicle-to-Vehicle (V2V) Communications

This report focuses on the channel estimation problem in IEEE 802.11p based vehicle-to-vehicle (V2V) communications, which is very challenging in view of the extremely time-varying characteristics of mobile channels. Specifically, we propose a novel channel estimator named constructed data pilot (CDP) estimator for the current communication standards, by fully exploiting the channel correlation...

Fuzzy Traffic Control with Vehicle-to-Everything Communication

Traffic signal control (TSC) with vehicle-to everything (V2X) communication can be a very efficient solution to traffic congestion problem. Ratio of vehicles equipped with V2X communication capability in the traffic to the total number of vehicles (called penetration rate PR) is still low, thus V2X based TSC systems need to be supported by some other mechanisms. PR is the major factor that affe...

Low Complexity Channel Estimation Method for IEEE 802.11p Vehicle Communications

Modern Intelligent Transportation System (ITS) uses the wireless communication technologies to increase the traffic safety and the transportation efficiency. However, the doppler effect and the multipath fading problems severely attenuate the received signal in the vehicle communication environments. Therefore, channel estimation is a critical issue should be solved properly to improve the Bit ...

Ray-tracing for Vehicle-to-vehicle Communications

A comprehensive model of the transmission channel between moving vehicles in realistic environments is presented in this paper. The approach consists of tree major parts: the modelling of the road traffic, the modelling of the environment adjacent to the road and the actual modelling of the wave propagation between the vehicles. A ray-tracing approach is used for the wave propagation, which all...
