In this letter, the algorithm given by Rouanne and Costello for the computation of the distance spectrum is improved for trellis-coded modulation schemes having uncoded bits, i.e., for trellis diagrams having parallel paths. It is shown that, when through a trellis corresponding to such kind of codes, all parallel transitions (labeled by signal selectors)(More)
In this paper the quasi-regularity property previously introduced by Rouanne and Costello for conventional trellis coded modulation (TCM) schemes is extended to space-time trellis codes (STTC) on slow fading channel for the first time. The minimum determinant and the first higher determinants of the distance matrix together with their multiplicities are(More)
