Abstract
A joint space-time (ST) coding and constellation rotation system is consider in the presence of imperfect channel state information. The combined system with two transmit antennas is shown to be more resistant to channel estimation errors than ST coding. Experiments involving channel estimation errors agree with the related theory reported in the literature.
