| 摘 要： | 论文将MIMO技术中的多天线思想与自适应OFDM技术相结合,提出一种新型的MIMO-OFDM自适应传输方案。通过信道矩阵的奇异值分解将多天线转化为多个并行的子信道,这样就可以把单天线OFDM的自适应传输技术应用于MIMO-OFDM系统。仿真结果表明,该系统性能比自适应SISO-OFDM系统有显著提高。

| Abstract: | This paper presents a novel adaptive transportation scheme for MIMO-OFDM system by combining the multi-antennas conception of the MIMO technology and adaptive OFDM technology.Through singular value deeomposition of channel matrix,the multi-antennas can be transformed into parallel subchanncels.Then the adaptive transportation scheme of SISO OFDM can be used in the MIMO-OFDM system.The results of simulation prove that the performance of the adaptive MIMO-OFDM system is better than the adaptive SISO-OFDM system. |
