Abstract 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 [2] is designed specifically to increase the minimum determinant. The branches of the outer trellis code are labeled with these partitions. Viterbi algorithm is applied for trellis decoding. In order to compute the branch metrics a sphere decoder is used. The general framework for code optimization is given. Performance of the proposed scheme is evaluated by simulation and it is shown that it achieves significant performance gains over uncoded Golden code. 1.
