| 摘 要： | 基于对窄带多输入多输出(Multiple Input Multiple Output,MIMO)技术和正交频分复用(Orthogonal Frequency Division Multiplexing,OFDM)技术的分析研究,发现二者具有相结合的可能性和现实性。通过建立二者结合的系统模型(MIMO-OFDM),给出该系统的空时编码方案。借助计算机仿真分析发现,结合后的MIMO-OFDM系统较传统的OFDM系统,可靠性获得提升。可见MIMO-OFDM系统的空时编码技术是一种提高通信质量的有效方法。

| Abstract: | Based on the analysis of narrowband MIMO（Multiple Input Multiple Output） technology and OFDM（Orthogonal Frequency Division Multiplexing） technology.It can be found that these two systems have the possibility and reality of combination.With an established MIMO-OFDM system model,the system＇s space-time coding scheme is given.Computer simulations shows that this system could enhance the system reliability,comparing with traditional one,obviously,MIMO-OFDM system of space-time coding is an effective way to improve the communication quality. |
