    "abstract": "A new shaping technique called coset shaping for coded QAM and PAM signaling is introduced and analyzed. This technique can be applied not only to information bits but also to parity bits without incurring additional complexity costs. It is proven that as the length of the error-correcting code and the modulation order tend to infinity, the gap to capacity for the proposed shaping scheme can be made arbitrarily small. Numerical results and comparisons for the shaping scheme, along with nonbinary LDPC-coded QAM signaling, are presented.",
