heal.abstract	This paper presents a channel estimation scheme that is efficiently designed for multiple transmit antennas, capable of operating in time varying and frequency selective propagation channels. The evaluation has been performed over the spatial channel model developed for MIMO simulations according to 802.16e case of 3GPP.25.996, taking also into account all IF and RF stages. Orthogonality has been applied in spacefrequency dimension for preamble, pilot, as well as for the data symbols. In 4G multicarrier systems, multidimensional orthogonal coding design turns into a key factor for the performance of the system, something which is quite challenging in highly time-variant propagation channels. The proposed estimation approach is efficient in minimization of the processing requirements at the receiver by estimating only the timevarying channel properties. 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.	en
