- W3208734163 abstract "Sparse code multiple access (SCMA) technology is a new type of Non-Orthogonal Multiple Access (NOMA) technology for next-generation mobile communications. Aiming at the poor bit error rate (BER) performance of Max-Log messaging scheme (MPA) based on log domain in SCMA technology. In this paper, the user node message and the resource node message are updated simultaneously, the threshold value is set and the stability judgment of the user node is increased, and the above two methods are combined. Three improved multi-node detection algorithms, namely, S-Max-Log-MPA, T-Max-Log-MPA, and S-T-Max-Log-MPA, are proposed. Through simulation, the BER performance of these three algorithms is obtained and their performance characteristics are compared and summarized." @default.
