Performance evaluations of channel estimations in IEEE 802.11p environments

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. The channel models in the simulation are referencing HIPERLAN/2.
