摘要：
In this paper, we propose multiple trellis-coded differential unitary space-time modulation (MTC-DUSTM), by assigning k greater than or equal to 2 singal blocks to a single trellis branch. We present the derivation of the formulae for the pairwise error-event probability (PEP) and the bit error probability (BEP) for MTC-DUSTM. Design criteria and a systematic code design have also been proposed. When compared with the trellis coded differential unitary space-time modulation where k = 1 signal block is assigned to a branch, we demonstrate that MTC-DUSTM has a better BEP performance when the two schemes have the same number of states.
