The SCMA codebook design is based on star-QAM signalling constellations with operating several segmentations to generate the different user’s codebook while considering the MED maximization as the criterion design. In addition, we constructed the mapping matrix F using Progressive Edge Growth (PEG) algorithm which facilitate iterative decoding performance of the message passing algorithm (MPA). At the end, a comparison with similar studies is conducted on the MEDs of the designed codebooks.
