Summary:Multiple-input multiple-output (MIMO) combined with Orthogonal Frequency Division Multiplexing (OFDM) techniques has been received a great attention in recent years. It is also well-known that Space-Time Block Coding (STBC) is the typical approach to significantly increase diversity gain. In this paper, we present our own hardware design of MIMO-OFDM STBC systems based on Simulink platform which consists of DSP Simulink library, DSP builder library, FPGA Altera Development KIT. The Verilog HDL is built and generated by Quartus II software. The paper compares the quality of MIMO-OFDM STBC system on hardware using 4QAM modulation with different numbers of receiver antennas in MIMO multipath fading environments.
