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。
A concatenated coding scheme of linear block codes and spatio-temporal block codes is proposed. The soft-input soft-output decoding algorithm of space-time block codes at the bit-level is deduced, and an iterative translation between linear block codes and space-time block codes Code algorithm. The simulation results show that this scheme can obtain the maximum diversity gain while still obtaining larger coding gain than the existing schemes.
