摘要
本文提出了一种新的四天线准正交空时分组码的通用设计方法.与Jafarkhani提出的设计方法相比,本方法大大增加了四天线准正交空时分组码的可用码字.在此基础上,对准正交空时分组码进行了性能分析.仿真结果表明,本文提出的准正交空时分组码与Jafarkhani提出的准正交空时分组码具有相似的误码率,并且有些码字的误码率优于Jafarkhani提出的码字的误码率.
Abstract： In this paper, a novel general design method of quasi - orthogonal space - time block codes for four antennae is presented. Comparison with the design method offered by Jafarkhani, this method enlarges the number of quasi - orthogonal space- time block codes. The performance of these codes is also analyzed. The simulation results show that the performance of the codes designed by this method is similar to or better than that of the codes offered by Jafarkhani.
