Based on L. F. Wei s work (1984), the generalized trellis diagram oftrellis codes is defined, then the properties of rotationally invariant trellis codes with two-dimensional QAM constellations are discussed, and all the unequivalent signal assignments are given. Finally, rotationally invariant trellis codes are designed easily.
