Short Lattice-Based Shaping Approach Exploiting Non-Binary Coded Modulation



We study a lattice-based constellation shaping for high-order modulation exploiting non-binary forward error correction. It is demonstrated that the proposed lattice shaping combined with turbo trellis-coded modulation (TTCM) achieves about 0.5 dB gain over the conventional TTCM scheme.
