Auto-SCMA: Learning Codebook for Sparse Code Multiple Access using Machine Learning
2021 National Conference on Communications (NCC), 2021 Sparse Code Multiple Access (SCMA) is an effective non-orthogonal multiple access technique that facilitates communication among users with limited orthogonal resources. Currently, its performance is limited by the quality of the handcrafted codebook.

Semi-granted Sparse Code Multiple Access (SCMA) for 5G Networks (Invited Paper)
, 2018 Sparse Code Multiple Access (SCMA) is a promising non-orthogonal multiple access technology for 5G radio access networks. It improves the connectivity and capacity. However, the two multiple access methods of SCMA: granted and grant-free cannot dynamically match the real-time demands since the resources allocated for the granted method and grant-free ...

Sparse Code Multiple Access (SCMA)
, 2018 Sparse Code Multiple Access (SCMA) enables non-orthogonal transmissions of multiple users’ signals among code and power domain, which could greatly improve the spectral efficiency. Due to the sparsity of the multi-dimensional codewords, the low-complexity message-passing algorithm (MPA) can be adopted and near maximum likelihood (ML) performance for ...

FH-SCMA: Frequency-Hopping Based Sparse Code Multiple Access for Next Generation Internet of Things
2017 IEEE Wireless Communications and Networking Conference (WCNC), 2017 The next generation Internet of Things (IoT) is expected to support extremely diverse applications and terminals, which requires the massive connectivity. Unfortunately, current mobile communication systems with orthogonal multiple access technique can hardly satisfy this demand.

Radio resource allocation for uplink sparse code multiple access (SCMA) networks using matching game
2016 IEEE International Conference on Communications (ICC), 2016 In this paper, we study the codebook-based resource allocation problem for an uplink sparse code multiple access (SCMA) network. The base station (BS) assigns to each user a set of subcarriers corresponding to a specific codebook, and each user performs power control over multiple subcarriers.
