| 摘 要： | 本文分析了传统的JafarkhaniQOSTBC（准正交空时分组码）和基于星座旋转的JafarkhaniQOSTBC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。

| Abstract: | 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 conditions,the result shows that QOSTBC based on constellation rotation provides better performance than traditional QOSTBC without increasing decoding complexity. |
