A minimum mean square error estimation (MMSE) using a virtual pilot channel estimation scheme was proposed by our researchers for improving the error performance of the IEEE 802.11p. However, compared to the STA channel estimation scheme, the MMSE scheme cannot provide an acceptable error performance in a low SNR region. To alleviate this, we propose an adaptive channel estimation scheme, which selectively uses a channel estimation scheme that has an error performance in-between that of the STA and the MMSE, through a decision method using a long preamble. Simulation results demonstrate that the proposed scheme can select a better channel estimation scheme, thereby demonstrating an excellent performance over the entire SNR range of interest.
