摘要 MIMO(多输入多输出)和OFDM(正交频分复用)技术的结合可以实现高数据传送速率并具有强的可靠性。文中分别研究基于STBC(空时分组编码)与SFBC(空频分组编码)的MIMO-OFDM系统和在不同的车载速度和时延扩展变化时的误比特率变化情况,结果表明:在不同环境中只有选择合适的系统参数才能发挥系统的最佳性能。 The combination of Multiple-input Multi-output （MIMO） and Orthogonal frequency-division multiplexing （OFDM） could achieve high data transmission speed and strong reliability .This paper mainly discusses the variance of bit error probability of MIMO-OFDM based on space-time block code（STBC） and space-frequency block code （SFBC） when the vehicular speed and delay spread is changed respectively. The results show that the proper selection of system parameters could only give full play to the system performance in the different environment.
