In order to meet the requirements which are considered in OFDM system under high-speed mobile environment, lots of techniques have been studied. In mobile communication system, fading distortion affects the overall performance. Furthermore, the higher the velocity of any mobile system, the severer the effect of fading is. To solve this problem, in OFDM system, exact channel estimation can be an important method. Until now, several channel estimation methods such as PSAM and ESAE. We propose the channel estimation method which outperforms conventional methods. The analytical results demonstrate that the proposed system has better performance than the conventional methods.
