Abstract(in English) | In multi-user MIMO systems, a base station needs downlink channel state information (CSI) to each user to suppress interference. In time-varying environments, however, the channels at the actual transmission time are different from the ones obtained at the base station because we have delay. This deteriorates communication quality. To solve this problem, we have proposed a channel prediction scheme using a compressed sensing technique. This scheme can predict channels with high accuracy when scatterers are stationary. In real environments, however, this assumption does not hold. In this paper, we propose a prediction scheme which can deal with moving scatterers, and evaluate the prediction performance. |
