Abstract
This paper presents a channel estimation scheme that is designed for time variant propagation channels and it is efficient by means of mean square error (MSE) of channel estimation and tracking and its incorporation in a real MIMO system. Such schemes target in demanding applications with minimum data rates well above the conventional standards under pedestrian level of mobility. The evaluation has been performed over the spatial channel model developed for MIMO simulations according to 802.16e case of 3GPP.25.996. Orthogonality has been applied in space-frequency dimension for both preamble and pilot symbols, as well as for the data symbols, with the application of Alamouti's coding. The estimation scheme is efficient in minimization the processing requirements at the receiver by estimating only the time-varying channel properties, and the presented results refer to MSE of the estimator, as well as to overall performance of the system (BER) in various propagation channels, data rates and FEC modes.
