Codeword Position Index Based Sparse Code Multiple Access System [PDF]
IEEE Wireless Communications Letters, 2018 In this letter, a novel variation of sparse code multiple access (SCMA), called codeword position index based SCMA (CPI-SCMA), is proposed. In this scheme, the information is transmitted not only by the codewords in M point SCMA codebook, but also by the indices of the codeword positions in a data block.
