Abstract
In this paper, we illustrate an orthogonal space-time block code (OSTBC) concatenated with trellis-coded modulation (TCM) model, for information transmission over a multiple-input multiple-output (MIMO) channel with 2 transmit antennas and 1 receive antenna. We establish the model of TCM-OSTBC concatenation using the SIMULINK. Also, the establishment of an independent TCM model and OSTB model are shown in order to compare with the concatenation scheme. Finally, the performance simulation diagram under three schemes is given. As expected, the simulation result clearly shows, the performance of concatenated OSTBC with TCM is better than TCM or OSTBC.
