It is shown that larger coding gains are achieved, outperforming the binary competitors by more than 0.3\u2009dB on the additive white Gaussian noise channel (AWGN). In the short block length regime, the designed codes gain more than 1\u2009dB with respect to the binary protograph LDPC codes recently proposed for the next generation up\u2010link standard of the Consultative Committee for Space Data Systems.
