SCMA CODEBOOK DESIGN BASED ON GRADIENT ASCENT ALGORITHM
Sparse Code Multiple Access (SCMA) is a non-orthogonal multiple access scheme, which improves spectrum efficiency. SCMA codebooks determine the bit error rate (BER) performance. There are various methods of constructing codebooks, but most of them are based on the formation of a mother constellation...
