A Low Complexity Detection Algorithm for Fixed Up-Link SCMA System in Mission Critical Scenario.
IEEE Internet of Things Journal(2018)
摘要
Sparse code multiple access (SCMA), as one of the most promising candidate techniques for the fifth generation communications system, is a nonorthogonal multiple access scheme which can provide large scale connections. Its philosophy is to map coded bits directly to multidimensional sparse codewords, and the message passing algorithm (MPA) is utilized to detect the multiuser signals. However, the ...
