Sparse code multiple access(SCMA) is a novel non-orthogonal multiple access scheme to face the future 5G communication. In allusion to the problem that sparse code multiple access(SCMA) system based on a logarithm-domain MAX-Log message passing algorithm(MPA) for multiuser detection has lower detection performance. this paper adopts a method that the message updating formula of the re... https://parisnaturalfoodes.shop/product-category/alkaline-pitcher-black/
