| 摘 要： | 为研究天线选择下准正交空时分组码(QSTBC)系统信道容量的改善程度,以TBH码为例推导出平均信噪比表达式,并以此作为天线选择的准则,计算出QSTBC系统容量.仿真结果表明:无论采用何种QSTBC码,天线选择下的准正交系统的信道容量都将明显增加.

| Abstract: | To investigate the improvement degree of channel capacity of quasi-orthogonal space-time block code (QSTBC) system based on antenna selection,TBH code was selected and its expression of average signal-to-noise ratio was deduced,which was used as the criteria for antennas selection to calculate the channel capacity of QSTBC system. Simulation results show that the channel capacity of QSTBC system with antennas selection is improved obviously. |
