循环前缀截去位置对频域插值性能的影响

In this paper, the effect of the removal position of the cyclic prefix on the linear interpolation is studied. The study shows inter symbol interference will not be involved when the cyclic prefix is removed in advance. However, the simple linear interpolation will introduce the some error between the channel estimation and the practical channel information. With the increase of the preact, the system performance degrades meanwhile. When the removal of the cyclic prefix is delay, inter symbol interference will be introduced.
