Unitary space-time codes from group codes: permutation codes variant II

Space-time coding was developed for use in multiple-antenna wireless communications to achieve high data rate and low error probability. The design of a full diversity space-time code with high coding gain and simple encoding-decoding algorithm poses a particularly challenging problem. In this paper, we present new full diversity unitary constellations, based on permutation codes variant II for differential unitary space-time modulation with two transmitter antennas. Simulations show that the proposed constellations have excellent performance at high signal-to-noise ratio, and also outperform constellations obtained from the dicyclic group, cyclic group, orthogonal design, parametric code and numerical method.
