| 摘 要： | 给出了自适应调制编码（AMC）的MIMO系统模型,分析了一种MIMO系统中自适应编码调制的方法,推导出系统的平均吞吐量和平均误码率,同时分析了时延对系统性能的影响。仿真结果表明,与SISO系统相比,联合正交空时分组码（O-STBC）的多天线自适应技术不仅提高了系统的平均吞吐量,而且对系统时延具有一定的顽健性。

| Abstract: | Given Adaptive Modulation and Coding(AMC) system model in the MIMO system,analyzed adaptive approach of MIMO system,derived out the average throughput and average bit error rate of the adaptive MIMO system,an the same time analyzed the time-delay on system performance.Compared with the SISO system,simulation results show that multi-antenna adaptive technology with orthogonal space-time block codes(O-STBC) not only increases the average throughput of the system,but also has some immunity to the time-delay. |
