“…In contrast, in SCMA bits are directly mapped to multidimensional complex codewords from predetermined codebooks. SCMA does not repeat QAM symbols but instead provides shaping gain through a multidimensional constellation design [17]. One similarity between these two systems is the small number of dimensions required to transmit data, resulting in a very small number of codewords in SCMA.…”
