Abstract

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