Scma github Currently, its performance is limited by the quality of the handcrafted codebook. Sparse Code Multiple Access (SCMA) is an effective non-orthogonal multiple access technique that facilitates communication among users with limited orthogonal resources. Li, L. Matlab simulation code for uplink polar coded SCMA system. Lei, and C. For this system, we first design the encoding method of systematic joint parity check and CRC-aided (PCCA) polar code. As an evolved variant of code division multiple access (CDMA), multiple users in SCMA are separated by assigning distinctive codebooks which display certain sparsity. The SCMA allows for both overloaded users and low complexity. in Electrical and Computer Engineering. Pan, E. May 14, 2021 · Sparse Code Multiple Access (SCMA) is an enabling code-domain non-orthogonal multiple access (NOMA)scheme for massive connectivity and ultra low-latency in future machine-type communication networks. We propose Auto-SCMA, a machine learning based approach that learns the codebook using gradient descent while using a Message Passing Algorithm In SCMA, the constellation mapper and the spread procedure are merged together to turn coded binary bits into multidimensional code-words and then these codewords are modulated on the OFDM channels in a sparse way [19]. D. Present permutation-based SCMA encoding/decoding algorithms for use in the researches of new schemes for 5G telecommunication standard. "Z.
