| Abstract | Dramatic increase in the traffic flow raises demand on innovative technologies that can improve safety and efficiency of transportation systems. Road safety can be substantially enhanced by the deployment of wireless communication technologies for vehicular networks, which enable new services such as collision detection and collision avoidance, traffic management, adaptive traffic control and further communication facilities between moving vehicles. Aiming at providing reliable wireless communications for vehicular networks the IEEE 802.11p standard will serve as an underlying protocol for future inter-vehicular applications worldwide. The research community has already started analyzing the IEEE 802.11p link-layer performance by using simulation tools and real-world experiments, but in spite of the increased academic and industrial research evaluation of the standard robustness in high-mobility scenarios still remains a big challenge. This thesis presents an implementation of a complete Orthogonal Frequency Division Multiplexing (OFDM) physical layer in Matlab SIMULINK, designed according to the specification in the draft amendment IEEE 802.11p. After a brief introduction to vehicular communications together with the ongoing standardization activities and the promising applications, I describe the implementation of the transceiver and outline the methodology that was used during the development process. In order to investigate the performance and reliability of the physical layer, several realistic propagation channel models, as well as one reference channel model are considered. Finally design parameters and useful optional extensions for the receiver that are crucial for performance optimization of vehicular communication systems are analyzed. Performance gains achieved with extended receiver design, as well as influence of propagation channel parameters on the overall system behavior are demonstrated based on numerical simulation results. |
