| 摘 要： | 提出基于Galois理论的空时分组码(STBC)，该STBC是线性的，能够通过球形译码算法或任何干扰对消算法进行译码．仿真结果表明，基于Galois理论的STBC系统比正交STBC系统以及未编码系统的性能曲线要好，当SNR增大时，正交STBC系统以及未编码系统的BER与所提出STBC系统的BER之差值也增大。

| Abstract: | This paper proposed space-time block codes (STBC) based on Galois theory. These codes are linear, which can be decoded via the sphere decoding algorithm or any interference cancellation algorithm. The simulation results show that the performance of the space-time block code system based on Galois theory is better than that of the orthogonal space-time block code system and the uncoded system. When the SNR increases, the difference between the BER of the orthogonal STBC system and that of the STBC system in this paper is increased. Also, the difference between the BER of the uncoded system and that of the STBC system in this paper increases with the SNR. |
