Abstract :
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.
