2014 ITE Technical Report  
In OFDM transmission , perforrriance is degraded by the existence oftime domain impulsive noise . Channel estimation scherne using pilot symbols in the impulse noise environment is proposed in this paper. With the increase in the number ofpilot symbols used 欺 chamel estimation , the estimation accuracy is improved , but the transmission e 価 ciency is lowered . Therefore , in order to increase the transmission efficiency, the scheme ofperforming channel estimation using only the pilot symbols of
