Trellis-coded M-ary orthogonal modulation
Proceedings IEEE Symposium on Computers and Communications, 2002We have introduced the trellis-coded M-ary (M=32) 4-dimensional (4-D) orthogonal modulation scheme. Here, a rate 4/5 convolutional encoder generates one of 32 possible symbols every T seconds. Then the signal mapping for 32 symbols is performed by a M-ary 4-D orthogonal modulator.

Trellis-coded modulation with multidimensional constellations
IEEE Transactions on Information Theory, 1987Trellis-coded modulation schemes using four-, eight-, or 16 -dimensional constellations have a number of potential advantages over the usual two-dimensional schemes: a smaller constituent two-dimensional constellation, easier tolerance to phase ambiguities, and a better trade-off between complexity and coding gain.
