Abstract: This thesis investigate and propose a large class of bandwidth efficient trellis coding schemes for the unitary space time modulation (USTM) in a non-coherent MIMO system, where the channel state information is not known both at the transmitter and the receiver. We first proposed trellis-coded USTM (TC-USTM), and performed the error performance analysis to obtain the design rules for a good trellis coding scheme. Then by exploiting the dissimilarities between distinct signal points in a constellation, we proposed a systematic ``mapping by set partitioning" strategy for the TC-USTM. We also proposed the multiple trellis-coded USTM (MTC-USTM), where each trellis branch is assigned multiple USTM signals. A systematic set partitioning scheme is developed for the k-fold Cartesian product of the USTM signals. We also extended the above trellis coding schemes to the differential USTM, which operate in a slow Rayleigh flat fading channel.
