| 摘 要： | 准正交空时分组码可以牺牲一定的分集增益和解码的简单性,来避免当天线数目大于2时正交空时分组码码率下降的缺点。基于准正交空时编码的优点,为了进一步提升性能,提出一种新的4天线准正交空时分组码,并与RS码进行级联编码。仿真表明这种新的编码方法可以保证在复杂度不是很高的前提下,相比Jafarkhani码、TBH码和该广义复正交码具有更低的误码率。

| Abstract: | Quasi-orthogonal space-time block codes (QOSTBC) can sacrifice certain diversity gain and the decoding of simplicity, avoid the transmission rate of the faults when the line number are greater than 2. based on the advantages of quasi- orthogonal space-time coding, in order to further improve performance, this article puts forward a new 4 antenna quasi -orthogonal space-time coding and joints coding with RS code. Simulation shows that this new coding method can guarantee under the premise that the complexity is not high, compared with Jafarkhani code and TBH code and the proposed generalized complex orthogonal code has a lower error rate. |
