摘要

推导了空时格码(STTC)构造的改进准则。在此基础上，提出了一种基于4PSK的串行级联卷积码(SCCC)与直接映射和灰度映射相结合的STTC构造方法。仿真结果表明，采用灰度映射的SCCC-STTC比直接映射的SCCC-STTC要好得多，采用灰度映射的SCCC-STTC优于S. Baro等人提出的改进sttc(参见IEEE common)。《书信》，第4卷，第20-2页，2000年)。SCCC-STTC具有良好的性能和易于施工。

An enhanced criterion for space-time trellis code and serially concatenated convolutionally coded STTC

An enhanced criterion for space-time trellis code (STTC) construction is deduced. Then a new kind of STTC construction is proposed using serially concatenated convolutional code (SCCC) with 4PSK jointly with direct mapping and Gray mapping. Simulation shows that SCCC-STTC with Gray mapping is much better than that with direct mapping and SCCC-STTCs with Gray mapping outperform the improved STTCs proposed by S. Baro et al. (see IEEE Commun. letters, vol.4, p.20-2, 2000). SCCC-STTC has good performance and is easy to construct.
