In this paper, we present a multidimensional trellis coded modulation scheme for a high rate 2 2 multiple-input multiple-output (MIMO) system over slow fading channels. Set partitioning of the Golden code is designed specifically to increase the minimum determinant. The branches of the outer trellis code are labeled with these partitions and Viterbi algorithm is applied for trellis decoding. In order to compute the branch metrics, a sphere decoder is used. The general framework for code design and optimization is given. Performance of the proposed scheme is evaluated by simulation and it is shown that it achieves significant performance gains over the uncoded Golden code.
Trellis coded modulation using a set partitioning of the Golden code is studied in REF , where a systematic design approach is proposed: partitions of the Golden code with increasing minimum determinant correspond to lattice partitions, which are labeled by using a sequence of nested binary codes.
