摘要

为了满足高速移动环境下OFDM系统的要求，人们研究了许多技术。在移动通信系统中，衰落失真会影响系统的整体性能。此外，任何移动系统的速度越高，衰落的影响就越严重。为了解决这个问题，在OFDM系统中，精确的信道估计是一个重要的方法。提出了一种优于传统信道估计方法的信道估计方法。分析结果表明，该系统比传统的PSAM和ESAE方法具有更好的性能。

A novel channel estimation method for OFDM in high-speed mobile system

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.
