Abstract :
This paper proposes a novel space diversity assisted OFDM receiver with Doppler spread compensator. A linear array antenna is set up on the vehicle. The proposed compensator estimates the received signal at the point that does not move with respect to the ground during the observation period. Computer simulation results show that the proposed scheme can mitigate the performance degradation due to Doppler spread.
