| 摘 要： | 提出了线性分组码与时空分组码的级联编码方案,推导了时空分组码在比特级上的软输入软输出译码算法,进而给出了在线性分组码和时空分组码之间进行迭代译码的算法。仿真结果表明这种方案与现有方案相比在能够获得最大分集增益的同时还能获得更大的编码增益。

| Abstract: | A concatenated coding scheme, including both linear block codes and space -time block codes, is developed in this dissertation. Based on the introduction of soft in soft out decoding algorithm of space - time block codes, an iterative decoding algorithm is invented, combining both linear block codes with space - time block codes. The simulation results show that compared with other similar concatenated schemes, this coding scheme can achieve more coding gain, meanwhile, maximum diversity gain acquired. |
