Abstract :
We present a systematic method for combining rotational invariance and punctured codes for use with TCM, and discuss a new perspective on the class of punctured codes. We present a rotationally invariant (RI) encoding/decoding structure. We also describe a method of encoding, using any transparent binary convolutional code, that results in a RI trellis code for applications to QPSK and QAM modulation
