| 摘 要： | 在对多带（MB）OFDM UWB通信系统进行研究分析的基础上,提出一种基于空时分组码（STBC）的多输入多输出（MIMO）MB-OFDM超宽带通信系统,并详细介绍了系统模型和空时码的编译码原理,对系统性能进行了仿真。仿真结果表明,在改进的S-V多径信道环境下,和传统空时分组码相结合的MB-OFDM系统不仅具有更高的信道容量和分集增益,而且误码性能有所提高。

| Abstract: | Based on study of multi-band OFDM system,a new MIMO-MB-OFDM communication system based on STBC is proposed. This paper discusses the system model and coding/decoding principle of STBC,and finally gives the simulation of system performance. Simulation results indicate that,under the modified S-V channel model,the proposed system has a increase in the channel capacity and obtains better diversity gain and BER performance. |
