| 摘 要： | 设计了发射天线数分别为8和6、码率为3/4的极化准正交空时分组码,对星座图进行最佳角度旋转,接收机采用成对译码算法,并对未旋转-极化、旋转-极化、未旋转-传统、旋转-传统这4种准正交空时分组码进行了仿真比较.结果表明,在相同条件下,当采用双极化天线时,星座图旋转对系统误码率性能改善不明显;当采用单极化天线时,旋转对系统误码率性能改善明显. |
| 关 键 词： | 准正交设计 空时分组码 误码率 旋转星座 成对译码 |

| Abstract: | A new kind of rate 3/4 space time block code based on quaternion quasi-orthogonal and the quasi-orthogonal polarization space time block code with signal optimal constellation rotation for eight and six transmit antennas were de- signed. The pair-wise decoding algorithm was adopted at the receiver. The simulation and comparison among polarization quasi-orthogonal, rotational polarization quasi-orthogonal, quasi-orthogonal and rotational quasi-orthogonal were given respectively. The results show that there i... |
