摘要
本文分析了传统的Jafarkhani QOSTBC(准正交空时分组码)和基于星座旋转的Jafarkhani QOSTBC的编、译码方案,并仿真了不同条件下OSTBC(正交空时分组码)、传统QOSTBC和基于星座旋转的QOSTBC的性能。仿真结果表明,在不增加译码复杂度的情况下,基于星座旋转的QOSTBC能够获得比传统QOSTBC更好的性能。
This paper analyses the encoding and decoding scheme of traditional QOSTBC （ quasi-orthogonal space-time block code） and QOSTBC based on constellation rotation technique. After computer simulates the performance of OSTBC, traditional QOSTBC and QOSTBC based on constellation rotation in different condi- tions, the result shows that QOSTBC based on constellation rotation provides better performance than tradition- al QOSTBC without increasing decoding complexity.
