It is generally difficult to estimate rapid time-frequency variant channels in IEEE802.11p systems due to insufficient number of pilots in a data packet. To resolve such a problem, advanced channel estimation schemes have been developed in literature. However, their performance has mostly been proven through computer simulations, which is insufficient for reflecting the actual road environments. In this paper, we introduce the result of our field trials based on the software defined radio testbed to evaluate the performance of four celebrated channel estimation schemes, namely, LS, STA, CDP, and TRFI in various vehicle-to-vehicle communication environments.
