MIMO-OFDM system, which is the combination of MIMO and OFDM technology, can live up to a high data transmission rate with reliability through diversity. MIMO-OFDM with STBC has excellent performance against Multi-path effects and frequency selective fading, what's more, the BER and the coding complexity is low. In this paper, a simulation model of MIMO-OFDM system based on STBC is built and transmission performances under different channels are analyzed. The simulation results show that the MIMO-OFDM system based on STBC outperforms other MIMO-OFDM system without STBC in BER performance.
