Abstract :
Space-time codes based on rings of integers suitable for QPSK constellations are presented for time-varying flat Rayleigh fast fading channels. Furthermore, a comparison between space-time ring TCM codes and the best known space-time codes for time-varying channels has revealed that the former offers a significantly better trade-off between coding gain and decoder complexity
