    We present the study and implementation of a 2 * 2 MIMO STC wireless OFDM system. Synchronization and channel estimation algorithms have been inserted in this implementation. The latter is the main focus of the work presented in this paper. The VHDL FPGA implementations have been applied in Elektrobit's OFDM test environment for 4G MIMO systems (EB4G) which consists of high-speed, FPGA-based programmable units. The verification of the design and intensive measurements under various ETSI BRAN channels have been performed using the Elektrobit Propsim C8 hardware multichannel emulator. The performance follow those of floatingpoint simulations. The implementation shows the performance attainable by such MIMO techniques in practical conditions and it also runs much faster than software simulations. The design allows further developments and studies towards 4G types of system like OFDMA, for example, with minor changes, as well as different types of impairments, in a quick and practical manner.
