Abstract

It is necessary to design an optimal method of partitioning a unitary space-time (UST) signal set for trellis coded unitary space-time modulation (TC-USTM). The unique features of these UST signals have necessitated a different partitioning methodology from that of the conventional two dimensional constellations. In this letter, we suggest a well-ordered set partitioning through a novel subset-pairing strategy, for an arbitrary UST signal set. This way leads to a geometrically coherent partitioning, i.e., subsets of the same size (order) have identical intra-distance profiles. According to this partitioning, the resulting TC-USTM can get a minimum bit error probability.
