摘要

介绍了一种基于FFT的OFDM系统高迁移率算法，该算法能以较低的复杂度补偿时变信道中的多普勒频移。我们首先提出了一种复杂度与FFT相似的信道矩阵反演算法，然后引入了一种基于匹配追踪算法的信道矩阵构造。

High mobility in OFDM systems based on FFT

A high mobility algorithm is introduced for OFDM systems based on the FFT which can compensate Doppler shifts in time-variant channels with low complexity. We first propose a channel matrix inversion algorithm with a complexity similar to FFT and then introduce a channel matrix construction based on matching pursuit algorithm.
