| 摘 要： | MIMO-OFDM技术不仅能够实现很高的传输速率而且通过分集实现很好的可靠性.设计了基于MIMO-OFDM技术四发多收天线的系统,针对随着收发天线数量增多接收机编码和译码算法复杂度随之提高的问题,选择适合多天线技术且具有低复杂度的正交空时分组码技术,接收端采用最大似然译码,调制采用多进制相移键控。通过仿真验证了该方案设计正确,证明了系统具有良好的差错性能和较高的频谱利用率。

| Abstract: | The technology of Multipe-input Multiple-output-Orthogonal Frequency Division Multiplexing(MIMO-OFDM) has been documented as an attractive means to achieve high data rate transmissions and high reliability by diversity techniques.In this paper,the four-transmit antenna and multiple-receive system based on MIMO-OFDM technique is designed. The orthogonal space-time block coding technology with low complexity is used,which can solve the problem of multiple antenna system that with the sum of transmit and recei... |
