SCMA Uplink Decoding with Codebook Collision
2017 IEEE 86th Vehicular Technology Conference (VTC-Fall), 2017Sparse code multiple access (SCMA) is a non-orthogonal multiplexing technique proposed to the 5G mobile communication system, which can improve the system performance in massive connectivity scenarios. However, during the random access phase of the SCMA system, the codebook used by a user is unknown to the base station.

The goals of this conference (and those of “SCMA I”) [FB1992] were three fold. i) To expose statisticians to the statistical challenges posed by the explosive growth in the amount and complexity of astronomical data and in astrophysical theory and experimentation during the second half of this century.

Uplink SCMA System With Multiple Antennas
IEEE Transactions on Vehicular Technology, 2017Sparse code multiple access (SCMA) is a codebook-based nonorthogonal multiple access that exploits the coding gain of designed codebooks and the near-optimum performance of belief-propagation (BP) detection. In this paper, we study an uplink SCMA system equipped with multiple receive antennas utilized to get a diversity gain.

Performance Study of SCMA Codebook Design
2017 IEEE Wireless Communications and Networking Conference (WCNC), 2017Sparse code multiple access (SCMA) is a non- orthogonal codebook (CB) based multiple access scheme, proposed to cope with the heterogeneous and challenging performance requirements for mission critical communication and massive machine-type communication (MTC) in the fifth Generation (5G) wireless system. In this paper, the performance of SCMA has been

An Uplink SCMA Scheme Combined with Interleaving
2018SCMA is a novel, promising non-orthogonal multiple-access technique which adopts iterative detecting algorithms with affordable complexity. Current multiuser detection algorithms are mostly based on factor graph, which usually has a small number of variable nodes and function nodes and makes the girth of the factor graph small.
