Novel Channel Estimation Techniques in IEEE 802.11p Environments

2010 IEEE 71st Vehicular Technology Conference, 2010
The primary challenge in the current IEEE 802.11p draft standard is the weak performance in multipath environment. Hence a time-domain (TD) and frequency-domain (FD) channel estimation techniques that can enhance the performance of channel estimation are proposed in this paper.

Efficient content pushing in IEEE 802.11p vehicular environments

Proceedings of the 8th International Conference on Advances in Mobile Computing and Multimedia, 2010
Vehicular networking is a new field that is expected to be widely adopted in the near future. One of the key applications inherent to this novel communications paradigm is content delivery to on-board users. In this paper we focus specifically on broadcast-based content delivery. We propose a content delivery scheme that is optimized for performance in

Performance evaluations of channel estimations in IEEE 802.11p environments

2009 International Conference on Ultra Modern Telecommunications & Workshops, 2009
To solve the defect in IEEE 802.11p standard that coherence bandwidth is insufficient to estimate the channel state in rich scattering environment, hance a time domain channel estimation technique is proposed in this paper. This technique is based on least-square (LS) algorithm, and assisted by Zadoff-Chu sequence in symbol prefix and preamble.

Performance modeling of the IEEE 802.11p EDCA mechanism for VANET

2014 IEEE Global Communications Conference, 2014
This paper develops an analytical model for analyzing the access performance of the IEEE 802.11p EDCA mechanism. A 2-D Markov chain is first constructed to describe the backoff procedure of an AC queue and establish a relationship between the transmission probability and collision probability of the AC queue.

Standards for vehicular communication—from IEEE 802.11p to 5G

e & i Elektrotechnik und Informationstechnik, 2015
Standardization for wireless vehicular communication ensures, as in other domains, interoperability, supports regulations and legislation, and creates larger markets. For the initial deployment of vehicular communication, consistent sets of standards have been created, commonly named C-ITS in Europe and DSRC in the U.S., both relying on the WiFi ...

IEEE 802.11p Transmission Using GNURadio

2010
In this work we present an implementation of a fully functional IEEE 802.11p transmitter in software-defined radio. We describe the rapid-prototyping methodology that was used to implement the frame-encoder within the open-source GNU Software Radio (GNURadio) platform [1].
