Résumé: New space-time trellis-coded modulation (STTC) which best satisfies the design criteria proposed by Tarokh et al. over fast fading channels are presented. STTC with feedforward structure have been constructed by a systematic and exhaustive search. Simulation results and parameter comparison show that these codes offer a better performance on fast fading channels than other known codes while maintaining a comparable performance on slow fading channels.
