摘要 通过研究多输入多输出正交频分复用(MIMO-OFDM)系统的基本原理,设计了两发一收和两发两收的相应系统,其数字调制方式采用多进制相移键控调制,空时编码采用Alamouti方案,信道编码采用RS编码。利用Matlab软件对该系统进行了仿真,并分析了系统的差错性能。仿真结果表明,该方案设计正确,系统不仅具有较高的频谱利用率和较好的差错性能,而且具有较高的应用价值。 The basic theory of Multiple- Input Multiple - Output - Orthogonal Frequency Division Multiplexing （MIMO- OFDM）systems is studied,2Tx1Rx and 2Tx2Rx systems are designed in which Multi- phase Shift Keying （MPSK）is used as digital modulation, Alamouti Coding technology is used as spacetime coding, and Reed- Solomon（RS） coding is used as channel coding. The system is simulated by using Matlab, and system performance is analyzed. The simulation results confirm that the design scheme is feasible. The system has not only high spectral efficiency, but also low BER, and it has wide applications.
