A protograph-based low-density parity-check (LDPC) code design technique forbandwidth-efficient coded modulation is presented. The approach jointlyoptimizes the LDPC code node degrees and the mapping of the coded bits to thebit-interleaved coded modulation (BICM) bit-channels. For BICM with uniforminput and for BICM with probabilistic shaping, binary-input symmetric-outputsurrogate channels are constructed and used for code design. The constructedcodes perform as good as multi-edge type codes of Zhang and Kschischang (2013).For 64-ASK with probabilistic shaping, a blocklength 64800 code is constructedthat operates within 0.69 dB of 0.5log(1+SNR) at a spectral efficiency of 4.2bits/channel use and a frame error rate of 1e-3.
