2011 Third International Conference on Communications and Mobile …, 2011•ieeexplore.ieee.orgIn this paper we present a 2× 2 MIMO-OFDM real-time system based on Sundance's
Software Radio development kits, which includes TI DSP, Xilinx FPGA, ADC/DAC and RF
modules, etc. As a demonstration, we implement an MIMO-OFDM system, which is a
simplification version of two antennas IEEE802. 11n standard, on this platform to verify its
availability. At transmitter it contains OFDM packet generation, encoding of Alamouti STBC
and DUC, and DDC. At receiver, the system contains some necessary receiver algorithms …

In this paper we present a 2×2 MIMO-OFDM real-time system based on Sundance's Software Radio development kits, which includes TI DSP, Xilinx FPGA, ADC/DAC and RF modules, etc. As a demonstration, we implement an MIMO-OFDM system, which is a simplification version of two antennas IEEE802.11n standard, on this platform to verify its availability. At transmitter it contains OFDM packet generation, encoding of Alamouti STBC and DUC, and DDC. At receiver, the system contains some necessary receiver algorithms, such as OFDM synchronization, channel estimation, decoding of Alamouti STBC, soft demapper and other components. In addition, the designed platform has greater feasibility and can be used for performance evaluation of newly developed signal processing algorithms.
