Abstract :
Using the results of Forney´s (1988) squaring construction, this paper integrates the rotationally invariant multidimensional trellis coded modulation (MTCM) construction schemes of Wei (1987) and Pietrobon (IEEE Trans. Info. Theory, vol.IT-39, no.3, p. 325-336, 1993), et al. into a highly efficient construction procedure. This procedure can be used to construct QAM or MPSK based MTCM schemes. This paper demonstrates that the squaring construction allows us to deduce the coset representatives of a multidimensional constellation directly from a 2-D partition. A method is given for generating and ordering the coset representatives for rotationally invariant MTCM schemes
