| Abstract: | In this paper, an improved criterion for STTC construction is discussed. Next a new kind of STTC construction using serially concatenated convolutionally coded modulation with QPSK with Gray mapping is proposed. Simulation shows that Gray mapping is much better than direct mapping, and the serially concatenated convolutionally coded STTCs with Gray mapping outperform the classical STTC proposed by Tarokh or the improved ones proposed by Bro. The serially concatenated convolutionally coded STTC has good performance and is easy to construct. |
