| 摘 要： | 在未来的第四代移动通信中,基于多输入多输出（MIMO）天线系统的空时编码技术是改善无线通信性能,提高带限系统数据传输速率的一种理想选择,但由于正交空时分组编码不能保证满分集和数据全速率传输,提出了一种利用星座图旋转可获得全速率满分集传输的旋转准正交空时分组码的设计方法。仿真结果表明,这种方法在不增加译码复杂度的情况下,其误比特率无论在低信噪比还是在高信噪比条件下都要优于已有的准正交空时分组码。

| Abstract: | In the future fourth generation mobile communication,the space-time coding technique based on multiple-input and multiple-output(MIMO) antenna system is an ideal candidate for improving wireless communication performance and increasing data rates in systems with bandwidth constraints.However,the orthogonal space-time block code could not achieve full-diversity transmission at the full rate.In this paper,a design method of quasi-orthogonal space-time block codes which can achieve full rate full diversity tra... |
