Throughput enhancement for the 802.11p communication

One of the most important parts of the vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) communication is reliable transmission that allows the achievement of good throughput in the system. In terms of high system throughput, two issues need to be taken into consideration. First, accurate estimation that is crucial for the successful application of equalization and demodulation, since V2X channel characteristics are very time-varying. Second, properly chosen channel coding. This paper presents effective channel estimation that requires only a slight modification to the 802.11p standard pilot scheme and also presents the impact of turbo coding on system throughput.
