Abstract
The use of vehicle-to-vehicle (V2V) communication will be an integral part of intelligent transport systems (ITSs) and lots of work has been done for ITS channel modeling. In order to establish communication between vehicles-to-vehicles and between vehicles and roadside stations for surveillance and proper navigation, a reliable wireless channel is needed. But the strength of the received signal can change significantly depending on the absorbing, diffracting and scattering effects from the surrounding environment and high Doppler velocity making channel estimation even more difficult. Frequency domain equalization (FDE) is a very effective tool to resist frequency selective fading in high speed communications system, but its performance will be greatly degraded when suffering serious Doppler impact due to rapidly time varying channel condition. Based on the single-carrier system with FDE (SC-FDE), a FDE scheme is proposed in this paper to resist high Doppler spreading effect.
