Since the channel has slowly-varying delays and directions of arrival and fast-varying faded amplitudes, benefits can be obtained by space-time processing base these channel features. In this paper, the space-time subspace and amplitude tracking algorithms using adaptive filtering technique are proposed by taking a training-sequence-based OFDM system with transmitter diversity as a multi-slot communications system and the channel estimation performance is observably improved. At the same time, this paper gives some simulations and comparisons of the performance of the different tracking algorithms.
