摘　　要：MIMO-OFDM系统中应用自适应传输技术可以在保证一定系统可靠性的基础上提高系统的吞吐量。本文分析了MI-MO-OFDM系统模型,并通过MATLAB编程对自适应传输技术进行了仿真,与采用固定传输模式的通信方式进行了比较,仿真实验结果证明该方案具有良好的系统平均通过率。MIMO can be used with OFDM to improve performance and transmission rates. In this paper, the MIMO-OFDM system is analyzed. Considering that the fading of channel may degrade the MIMO-OFDM system performance, the adaptive transmission technique based on capacity estimation for MIMO-OFDM system is simulated, The simulation result shows that the proposed adaptive transmission technique improves the spectral efficiency of the system.
