结合STBC的V-BLAST多天线超宽带OFDM系统性能研究

内容简介：在对多带(MB)OFDM UWB通信系统进行研究的基础上,结合空时分组码(STBC)和空时分层码(V-BLAST)两者的特点,该文分析了混合型编码的多输入多输出(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,两者结合的多天线MB OFDM系统不仅具有更高的分集增益和传输效率,而且误码性能有所提高.

Abstract：According to the study of multi-band OFDM system,a new MIMO-MB-OFDM communication system based on mixed code is analysed by combining the advantages of STBC and V-BLAST. In this paper, we discuss the system model and the coded and decoded principles and finally simulated the system performance. Simulation results indicated under the revision S-V channel model, the system has obtained the higher diversity gain and transmission efficiency and the better BER performance.
