Abstract:

 

Sparse Code Multiple Access (SCMA) is a NOMA (Non- Orthogonal Multiple Access) technique based on the design of codebook, proposed to manage the varied and demanding performance for massive Machine-Type Communication (m-MTC) in 5G wireless communication systems. In SCMA, to enhance the Bit Error Rate (BER) with other performance parameters, the primary source is the codebook design that is generated based on Mother Constellation. This paper discusses the techniques of designing the codebook and algorithms, using specified Mother Constellation to enhance the bit error rate. It also explains the use of Deep learning for designing a codebook.
