Abstract :
At 28-Gbaud soft-coded POLQAM exhibits measured coding gain improvements of 1.5dB and 3.1dB for 12.5% and 30% code overhead, respectively, when moving from hard decision to soft decision FEC. Iterative demapping was mandatory to decode the LDPC code which was optimized for POLQAM by EXIT chart technique.
