Abstract
Space-time coding is well established for high data rate communications in wireless channels with perfect channel state information. On the other hand, the case where channel state information is unknown has received limited attention. Recently, a new signaling scheme called unitary space-time modulation has been proposed for the latter case. In this paper, we describe the use and design of trellis coded space-time modulation schemes that use unitary space-time constellations. Simulation results show that the proposed schemes improve the performance compared to uncoded transmission with the same spectral efficiency.
