| 摘 要： | 为了适应通信系统对高速率大容量的需求,设计了码率为2及1.5的非正交空时分组码。在此基础上,采用简化了的条件最大似然译码方法,可以大大降低译码复杂度。仿真结果表明,该编码设计具有接近实际信道容量的特点,并且其误比特率性能优于正交及准正交编码设计。

| Abstract: | In order to meet the needs of high-speed and large-capacity in communication system,the novel non-orthogonal space-time block code with code rates 2 and 1.5 were proposed,respectively.The simplified conditional maximum-likelihood algorithm is adopted to reduce the decoding complexity.The simulation results show that the channel capacities of proposed code are very close to the actual value,and the BER performance is better than that of the orthogonal and quasi-orthogonal codes. |

| Keywords: | space-time block code high rates channel capacity conditional maximum-likelihood decoding |
