Abstract

The vehicle-to-vehicle (V2V) communications channels are highly time-varying, making reliable communication difficult. This problem is particularly challenging because the standard of the V2V communications (IEEE 802.11p standard) is based on the WLAN IEEE 802.11a standard, which was designed for indoor, relatively stationary channels; so the IEEE 802.11p standard is not customized for outdo or, highly mobile non-stationary channels. In this thesis,We propose Channel estimation and tracking algorithms that are suitable for highly-time varying channels. The proposed algorithms utilize the finite alphabet property of the transmitted symbol, time domain truncation, decision-directed as well as pilot information. The proposed algorithm s improve the overall system performance in terms of bit error rates, enabling the system to achieve higher data rates and larger packet lengths at high relative velocities. Simulation results show that the proposed algorithms achieve improved performance for all the V2V channel models with different velocities, and for different modulation schemes and packet sizes as compared to the conventional least squares and other previously proposed channel estimation techniques for V2V channels.

Comments

All praise is due to Allah (God). I would like to express my gratitude towards my supervisor Dr.Karim Seddik. His way of thinking, fruitful contribution, support and understanding had made my M.Sc journey more beneficial and much easier. Also i would like to thank Dr.Ayman Elezabi for his guidance through out my graduate studies. I thank my parents so much for their support and for always pushing me forward that makes me has no choice other than to succeed. I would like to confess that without their support, i would never have been able to achieve so much. I especially want to thank my wife for being by my side and making me more confident and motivated to pursue my master’s degree. I am extremely grateful to General Nabil Elmohandes, for his support during my military service and making me able to pursue my studies.
