— This paper considers an efficient channel estimator for multiple transmit and receive antennas in multicarrier CDMA systems, capable of operating in time variant and frequency selective propagation channels. Orthogonality has been applied in space-frequency dimension. The evaluation has been performed over spatial channel models developed for MIMO(More)
This paper presents the design and evaluation of a channel estimation scheme that is efficient by means of both the mean square error (MSE) of channel estimation/tracking and its incorporation in a real MIMO system. The evaluation has been performed over the spatial channel model developed for MIMO simulations according to 802.16e case of 3GPP.25.996,(More)
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(More)
