摘要

本文提出了一种时变MIMO信道中频率偏移的盲估计方法。本文发现了时空数据具有独特的周期性。利用这种周期性推导出一种非常有效和简单的盲估计频率偏移量。与传统的数据辅助估计器相比，该估计器提供了更好的频率偏移估计。从而在很大程度上提高了接收机的性能

On blind estimation of frequency offsets in time varying MIMO channels

In this paper we propose a novel blind estimator of frequency offsets in time varying MIMO channels. Space-Time data has a unique periodic property which has been discovered in this paper. This periodicity is utilized to derive a very efficient and simple blind estimator of the frequency offsets. This estimator provides far better estimates of the frequency offsets than the conventional data-aided estimator. As a result it enhances the performance of receiver to a large extent
