- Abstract
- We propose the new pilot structure to support high speed vehicular channels. The proposed pilot structure is designed in consideration of the channel estimation performance and overhead. Simulation results show that the proposed pilot structure has good Mean Square Error(MSE) performance compared to conventional pilot pattern based on 802.16m standards at the velocity of 250 km/h.
