| Abstract: | In this paper, the MIMO system model and three criteria for space-time code design are introduced. Then, according to these criteria, combining trellis-coded modulation with space-time block code, a new kind of full-diversity full-rate space-time code called Trellis-Coded Modulation Space-Time (TCMST) block code and its trellis-sphere decoding algorithm are presented. Finally, the performance merit of TCMST block code is confirmed by Monte Carlo simulations and compared with other space-time block codes. |
