| 摘 要： | 给出了线性空时码同时能达到最大分集度和信道容量的符号传输率必须满足的条件.提出了一种新的空时分组码设计方法,由该方法设计得到的空时分组码为容量无损满分集度空时码,即它能提供满发送分集度,且含空时码等价信道容量达到MIMO系统容量.证明了许多已发现的容量无损满分集度空时分组码均为该方法的特例.对新得到的分组码的性能进行了仿真,并与其他空时分组码就平均误比特率做了比较,证实了其性能的优越性.

| Abstract: | Necessary condition for symbol transmit rate in which maximum diversity and channel capacity of linear space-time code are attained is given and a new systematic space-time block code design framework is proposed.The space-time block code constructed by this design framework is capacity lossless and full-diversity,that is,it can achieve the full transmit diversity and the capacity of the equivalent channel including the space-time code equals the multiple-input multiple-output(MIMO) system capacity.It is proved that the proposed design framework subsumes many of the existing capacity lossless and full-diversity space-time codes.The performance merit of the proposed block code is confirmed by simulation results and compared with other space-time block codes in terms of average bit error probability. |
