摘要
合并空时码和闭环发射分集技术是一种提高无线信道通信性能的有效方法.现将A lamouti空时码与发射天线选择技术相结合,即利用A lamouti空时码的基于线性处理的最大似然译码,且仅需要2个射频链路,减少了M IMO系统的复杂性.理论分析及仿真表明,采用A lamouti空时码与发射天线选择技术结合提高了系统的分集性能.
The combination of space-time codes and a closed loop transmission diversity technique is an efficient way to improve the performance of wireless communication channels. By the combination of STBC and transmission antenna selection, which adopts the maximum likelihood decoder based on linear processing, only two RF chains are needed, reducing the complication of the MIMO system. Theoretical analysis and simulations show that the technique improves the diversity gain.
