Rotationally invariant trellis code is a powerful method to overcome phase ambiguity without extra information.An efficient algorithm for constructing pair rates fully rotationally invariant trellis coded modulation in time-vary channels is presented in this paper.In addition,preliminary indications is provided on its performance.
