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
