摘要
依据空时分组码的复正交设计理论的推广,推导了基于坐标正交设计(ClOD)的空时码构造方法,并在准静态平坦Rayleigh衰落信道中,对802.16d(e)中使用的四发射天线基于CIOD的发射分集配置方案A进行了性能仿真,结果表明这些码具有较低的译码复杂性,与基于复数正交设计的空时分组码的译码复杂度相当,但性能要好。
Space-time codes based on coordinate interleaved orthogonal designs（CIOD） were put forward according to generalized orthogonal designs for space-time block codes. Simulations for transmit format A with 4Tx CIOD in 802.16e（d） were made under quasi-static Rayleigh flat-fading channel. The results show the performance of CIOD STC system is better than non-CIOD system with the same decoding complexity.
