Description
Summary:To solve the defect in IEEE 802.11p standard that coherence bandwidth is insufficient to estimate the channel state in rich scattering environment, hence 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.
