Sparse Autoencoder for Sparse Code Multiple Access

2021 International Conference on Artificial Intelligence in Information and Communication (ICAIIC), 2021
In the forthcoming 5G technology, Sparse Code Multiple Access (SCMA) is the most promising scheme that aims at improving spectral efficiency further and providing massive connectivity. The challenge behind implementing SCMA scheme is: constructing optimized codebooks in order to obtain minimum BER while keeping the receiver complexity minimum.

Sparse code multiple access

2013 IEEE 24th Annual International Symposium on Personal, Indoor, and Mobile Radio Communications (PIMRC), 2013
Multicarrier CDMA is a multiplexing approach in which modulated QAM symbols are spread over multiple OFDMA tones by using a generally complex spreading sequence. Effectively, a QAM symbol is repeated over multiple tones. Low density signature (LDS) is a version of CDMA with low density spreading sequence allowing us to take advantage of a near optimal ...

Sparse Code Multiple Access with Index Modulation

2020 IEEE/CIC International Conference on Communications in China (ICCC), 2020
In this paper, we study the application of index modulation (IM) to uplink sparse code multiple access (SCMA), and present a scheme called SCMA-IM. In the proposed SCMA-IM, the candidate resources of one user are partitioned into two groups. All the resources in the first group are utilized to transmit signals, and only part of resources in the second ...

Sparse Code Multiple Access Over Universal Filtered Multicarrier

IEEE Transactions on Vehicular Technology, 2021
In this paper, the uplink sparse code multiple access over universal filtered multicarrier (SCMA-UFMC) is studied. In SCMA-UFMC, each sub-band of UFMC is occupied by multiple users through SCMA. Note that the even-component of frequency domain (FD) received signal suffers from neither inter-sub-band interference nor inter-sub-carrier interference while

An Improved Uplink Sparse Coded Multiple Access

IEEE Communications Letters, 2017
Sparse coded multiple access (SCMA) has received considerable attention recently as a candidate multiple access scheme for 5G cellular systems. This letter proposes an improved uplink SCMA scheme where instead of the multi-dimensional constellation (MDC) mapping and a fixed number of nonzero elements per sparse codeword, a varying number of coded ...

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 ...
