Abstract

In this work the labelling diversity scheme is developed. The Binary Switching Algorithm is employed to find an optimized 2-dimensional labelling map of 16-QAM constellation, which, applied in conjunction with the best map for iteratively-decoded bit-interleaved space-time coded modulation (BI-STCM-ID), enhances the advantages of multi-antenna transmission. Properties of the proposed scheme are compared with the original BI-STCM-ID by means of Distance Spectrum, Extrinsic Information Transfer (EXIT) Chart and Asymptotic Coding Gain calculation. Afterwards they are verified by the Monte-Carlo simulations.
